Question

the volume of cube is 512 cm cube what is its total surface area

Answer 1

Volume of the cube = 512 cm³

Find the length of the side:

Volume = side³

side³ = 512

side = ∛512

side = 8 cm

Find the area of 1 face:

area = side²

area = 8²

area = 64 cm²

Find the total surface area:

Total surface area = 6 faces

Total surface area = 6 x 64

Total surface area = 384 cm²

Answer: The total surface area is 384 cm²

Answer 2

hey!


here is answer


given

volume of. cube= 512 cm cube

volume of. cube
$= {side}^{3}$


hence

$side ^{3} = 512$

$side = \sqrt[3]{512}$

$\sf{side = 8cm}$

total surface area of. cube= 6* side ^2


6*8^2

6*64



hence answer is

$\bf{384 \: cm ^{ 2}}$


hope it helps

thanks
