Volume of a cube:

Volume

=

side × side × side

solution

Each side of the cube is 8.5 yards long. Use the number 8.5 in the formula.

Volume	=	side × side × side

	=	8.5 × 8.5 × 8.5

	=	614.125

Now find the units. The lengths are measured in yards, so the volume is measured in cubic yards.

The volume is 614.125 cubic yards.
