Answer:
9.2 x 9.2 x 9.2 (778.688)
Step-by-step explanation:
When you are looking at a cube or 3D figure, most of the time you will have to multiply by the base, length, and height. Since this is a cube, all the sides are the same, so the base, length, and height are also the same. First multiply 9.2 x 9.2 to get 84.64. 84.64 (bxl) now must be multiplied by the height. 84.64 x 9.2 = 778.688.
