Question

The total surface area of a cube is 150cmsquare. Its volume is_______ cm3

Answer 1

Answer:

Total surface area = 150cm^2

$total \: surface \: area = 6 {l}^{2}$

$150 = 6 {l}^{2}$

$\frac{150}{6} = {l}^{2}$

$25 {cm}^{2} = {l}^{2}$

$\sqrt{25} = l$

$5cm = l$

$volume = {a}^{3}$

$volume = {(5cm)}^{3}$

$volume = 125 {cm}^{3}$
