Recall the formula for volume of a solid.
A
The volume of a rectangular prism with l length, w width, and h height can be calculated using the formula below. V=l wh We have been given that l= x, w= x, and h= x, so we have enough information to calculate the value of V.
Substitute values
a* a* a=a^3
The volume of the prism is equal to x^3, which corresponds to answer A.
