1. A blank of sheet material for forming a polygonal container, the blank comprising: two end panels, two side panels, and four corner panels connected in series along a plurality of fold lines, each of the four corner panels having a free bottom edge; anda plurality of bottom panels each extending from one panel of the end panels and the side panels, at least three bottom panels of the plurality of bottom panels each having a first outwardly angled portion and a first inwardly angled portion that cooperate to at least partially define a corner projection, each first outwardly angled portion is configured to extend proximate to a respective one of the free bottom edges when the container is erected such that each respective corner projection forms a portion of a bottom wall of the erected container, the plurality of bottom panels configured to define a locking slot and a locking tab that is insertable into the locking slot to form another portion of the bottom wall of the erected container. 2. A blank in accordance with claim 1, wherein the plurality of bottom panels comprises: a first bottom end panel extending from a bottom edge of a first end panel of the two end panels;a second bottom end panel extending from a bottom edge of a second end panel of the two end panels;a first bottom side panel extending from a bottom edge of a first side panel of the two side panels; anda second bottom side panel extending from a bottom edge of a second side panel of the two side panels. 3. A blank in accordance with claim 2 wherein the first bottom side panel defines the locking tab. 4. A blank in accordance with claim 2 wherein the locking slot is defined by the first bottom end panel, the second bottom end panel, and the second bottom side panel. 5. A blank in accordance with claim 4 wherein the first bottom end panel defines a first locking extension; the second bottom end panel defines a second locking extension; and the second bottom side panel defines a locking indentation. 6. A blank in accordance with claim 5 wherein the first locking extension, the second locking extension, and the locking indentation are configured to define the locking slot. 7. A blank in accordance with claim 1 further comprising a plurality of top panels each extending from one panel of the end panels and the side panels, the plurality of top panels configured to form a top wall of the container. 8. A blank in accordance with claim 7 wherein the plurality of top panels are configured to interlock using tabs and slots defined by the plurality of top panels to form the top wall. 9. A blank in accordance with claim 1, wherein each first outwardly angled portion is configured to be co-linear with a respective one of the free bottom edges when the container is erected. 10. A container formed from a blank of sheet material, the container comprising: two end walls, two side walls, and four corner walls connected in series along a plurality of fold lines, each of the four corner walls having a free bottom edge; anda bottom wall formed from a plurality of bottom panels each extending from one wall of the end walls and the side walls, at least three bottom panels of the plurality of bottom panels each having a first outwardly angled portion and a first inwardly angled portion that cooperate to at least partially define a corner projection, each first outwardly angled portion extends proximate to a respective one of the free bottom edges such that each respective corner projection forms a portion of the bottom wall of the erected container, the plurality of bottom panels configured to define a locking slot and a locking tab that is insertable into the locking slot to form another portion of the bottom wall. 11. A container in accordance with claim 10 wherein the plurality of bottom panels forming the bottom wall comprises: a first bottom end panel extending from a bottom edge of a first end wall of the two end walls; a second bottom end panel extending from a bottom edge of a second end wall of the two end walls; a first bottom side panel extending from a bottom edge of a first side wall of the two side walls; and a second bottom side panel extending from a bottom edge of a second side wall of the two side walls. 12. A container in accordance with claim 11 wherein the locking tab is defined by the first bottom side panel and the locking slot is defined by the first bottom end panel, the second bottom end panel, and the second bottom side panel. 13. A container in accordance with claim 10 further comprising a top wall formed from a plurality of top panels each extending from one panel of the end panels and the side panels. 14. A container in accordance with claim 13 wherein the top wall is formed by interlocking the plurality of top panels together using tabs and slots defined by the plurality of top panels. 15. A container in accordance with claim 10, wherein each first outwardly angled portion is co-linear with a respective one of the free bottom edges. 16. A method for forming a container from a blank of sheet material, the method comprising: rotating a plurality of wall panels about a plurality of fold lines to form a first side wall, an opposing second side wall, a first end wall, an opposing second end wall, and a plurality of corner walls that each have a free bottom edge; androtating a plurality of bottom panels with respect to the plurality of wall panels to form a bottom wall, the plurality of bottom panels defining a locking slot and a locking tab insertable into the locking slot, at least three bottom panels of the plurality of bottom panels each having a first outwardly angled portion and a first inwardly angled portion that cooperate to at least partially define a corner projection, each first outwardly angled portion extends proximate to a respective one of the free bottom edges when the container is erected such that each respective corner projection forms a portion of the bottom wall of the erected container. 17. A method in accordance with claim 16, wherein rotating a plurality of bottom panels with respect to the plurality of wall panels to form a bottom wall further comprises: rotating a first bottom end panel with respect to the first end wall; rotating a second bottom end panel with respect to the second end wall; rotating a first bottom side panel with respect to the first side wall; and rotating a second bottom side panel with respect to the second side wall. 18. A method in accordance with claim 17, wherein the locking tab is defined by the first bottom side panel and rotating a first bottom side panel comprises inserting the locking tab into the locking slot. 19. A method in accordance with claim 17, wherein rotating a plurality of bottom panels with respect to the plurality of wall panels to form a bottom wall further comprising defining the locking slot with the first bottom end panel, the second bottom end panel, and the second bottom side panel. 20.
