The volume of a cube equals its side cubed. Since the side of the cube is 12ft long, then its volume is given by:
[tex]V=(12ft)^3=1728ft^3[/tex]
Then, the volume of the cube, is:
[tex]1728ft^3[/tex]
5.
The volume of the prism equals the product of each of its dimensions. Then:
[tex]V=(7m)(2m)(3m)=42m^3[/tex]
Then, the volume of the rectangular prism, is:
[tex]42m^3[/tex]
