Question

find the total surface area of a cube if the volume of its is 216 cm cube​

Answer 1

Volume of cube = 216 cm cube

a^ 3 = 216

a = 6cm

TSA of cube = 6a^2

= 6×6×6

= 216 cm square.

Answer 2

✬ Total Surface Area = 216 cm² ✬

Step-by-step explanation:

Given:

• Volume of cube is 216 cm³.

To Find:

• What is the total surface area of cube?

Solution: Let the each side of cube be a cm. Then, the volume of the cube will be (a³) .

$\small\implies{\sf }$ a³ = 216

$\small\implies{\sf }$ a = √6 x 6 x 6

$\small\implies{\sf }$ a = 6 cm

★ T.S.A of cube = 6a² ★

$\small\implies{\sf }$ T.S.A = 6 x (6)² cm²

$\small\implies{\sf }$ T.S.A = 6 x 36 cm²

$\small\implies{\sf }$ T.S.A = 216 cm²
