Question

The surface area of a cube us 486cm2 its volume is

Answer 1

ANSWER. V≈729cm³..........

Answer 2

Answer:

Here's your answer

surface area of cube= 6a^2

$486 = 6 {a}^{2} \\ \\ \frac{486}{6} = {a}^{2} \\ \\ 81 = {a}^{2} \\ \\ \sqrt{81} = a \\ \\ 9 = a$

So the volume will be

$volume \: of \: cube \: = {a}^{3} \\ \\ {9}^{3} = 729 \\ \\ so \: the \: volume \: of \: cube \: is \: 729c {m}^{3}$
