Question

Find the surface area, in square inches, of a cube whose volume is 8 in³.

Answer 1

24 in^2

Explanation:

common math

Answer 2

• Surface area of cube is 24 in²

Explanation:

In this question we have given volume of cube that is 8 in³. But we know that volume of cube is a³. So ,

`\implies \: a {}^(3) = 8`

Now ,

`\implies \: a = \sqrt[3]{8}`

So , cube root of 8 is ,

`\implies \: \boxed{\bold{a = 2}}`

• Therefore, value of a is 2 inches .

Now , we are finding surface area of cube . We know that surface area of cube is 6a² . So ,

• 6 ( 2 )²

• 6 ( 4 )

• 24

`\pink{ \boxed{ Therefore, \: surface \: area \: of \: cube \: is \: 24 \: in ^(2) }}`
