Question

The function V(x)=x^3 may be used to find the volume of a cube with side of length x. Find the volume of a cube whose side is 22 inches.

Answer 1

The cube whose side length is 22 inches meaning for it x = 22 inches, and since the volume of a cube is given by

$V(x)=x^3$

For x = 22 this gives

$V(22)=22^3$$\rightarrow V(22)=22\times22\times22=\textcolor{#FF7968}{10,648.}$

Hence, the volume of a cube with side length of 22 inches is 10,648 cubic inches.
