Answer 2

Answer:

• Surface area of cube is 24 in²

Step-by-step 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

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