If #9# cubic blocks with a side length of #1/3# inches are needed to find the volume of a cube, what is the volume of the cube?
The wording of this answer confused me, but I think I might understand what it's getting at.
In order to calculate the volume of a cube you need to know the length of a single side. If 9 blocks are required to find the volume, then we must need all 9 blocks to measure a single side.
If we stack 9 block vertically (or line them up side by side), we get:
If a single side of the cube is 3 inches, then we can simply solve for area using the area formula
