Question

if volume of cube is 8000cm3 then find total surface of cube

Answer 1

• Given

• Volume of cube = 8000 cm³

• To find

• Total surface area of cube

• How to solve?

⇒

• We have the value of volume of cube. Firstly, we will use the formula of volume of cube and from there we will find the side of cube.

• Now, after finding the side of cube we will use the formula to find surface area of cube.

Formulae to be used -

• Volume of cube = (side)³
• Total Surface area of cube = 6 × side²

• Solution

Volume of cube = 8000 cm³

⇒ (side)³ = 8000

⇒ side = √8000

⇒ side = 20 cm

• Side = 20 cm

Total Surface area of cube = 6 × side²

⇒ 6 × 20

⇒ 120 cm²

• Total Surface area of cube = 120 cm²
