Question

The volume of cube is 64 cm³, then find the total surface area of cube is ?
1. 96 cm²
2. 48 cm²
3. 84 cm²
4. 76 cm²

Answer 1

Correct Answer - Option 1 : 96 cm²

Given:

The volume of cube is 64 cm³

Formula used:

Volume of cube = side³

Total surface area = 6 × side²

Calculation:

Volume of cube = side³

⇒ side³ = 64 cm³

⇒ side = ∛64

⇒ side = 4 cm

Total surface area = 6 × side²

⇒ 6 × 4 × 4

⇒ 96 cm2

∴ The total surface area is 96 cm².
