Question

the surface area of cube is 384 cm. find its edges and volume

Answer 1

$surface \: area \: of \: cube \: = 6 {a}^{2} \\ 384 =6 {a}^{2} \\ {a}^{2} = \frac{384}{6} \\ {a}^{2} = 64 \\ a = 8cm \\ volume \: of \: cube \: = {a}^{3} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = {8}^{3} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 512 \\ volume \: of \: cube \: is \: 512 \: {cm}^{3} \\ mark \: as \: a \: brainliest$
