Question

A special jacuzzi has a cube shape. If its volume is 343 feet cubed, what are the lengths of its sides?

Answer 1

a cube, will be like the one in the picture below, with all equal sides, and therefore with a volume of x³.

`\bf \textit{volume of a cube}\\\\ V=x^3~~ \begin{cases} x=side's~length\\[-0.5em] \hrulefill\\ V=343 \end{cases}\implies 343=x^3\implies \sqrt[3]{343}=x\implies 7=x`
