This is a cube because it's a figure with 6 squares faces.
Since the length, width, and height of a cube are all equal, we can find the volume of a cube by multiplying side × side × side.
So we can find the volume of a cube using the formula S³.
In the cube shown here, notice that we have a side length of 7.5 feet.
So plugging into the formula we have (7.5 feet)³ or
(7.5 feet) (7.5 feet) (7.5 feet) which is 421.875 ft³.
So the volume of the cube shown here is 421.875 ft³.
