Question

Pls give correct answer !

Answer 1

Volume (cube) = side × side × side
$volume \: = {side}^{3} = {s}^{3} \\ so \: since > \: a \: = side \: \\ and \: Vol = 8000 {ft}^{3}$
Volume (v) =
${a}^{3} = 8000 {ft}^{3} \\ \sqrt[3]{ {a}^{3} } = \sqrt[3]{8000 {ft}^{3} } \\ a = 20ft$
And you can check because 20 × 20 × 20 = 8000, bc 20 × 20 = 400, and 400 × 20 = 8000
