Question

A cube with an edge of length s has a volume of 512 cubic feet. How many feet long is s?

Answer 1

Answer:

\boxed{\text{8 ft}}  

Step-by-step explanation:

The formula for the volume of a cube is

V = s³

where s is the length of a side.

$\begin{array}{rcl}\\V&=&s^{3}\\\text{512 ft}^{3}& =&s^{3}\\\sqrt[3]{ \text{512 ft}^{3}} & = & s\\s & = & \textbf{8 ft}\\\end{array}\\\text{The length of one side is \boxed{\textbf{8 ft}} }$
