Question

The areas of three consecutive faces of a cuboid are 9 cm², 25 cm² and 36 cm², then the volume (in cm²) of 
1. 60
2. 90
3. 3000
4. 100

Answer 1

Correct Answer - Option 2 : 90

Given:

Areas of three consecutive faces of a cuboid = 9 cm², 25 cm² and 36 cm²

Formula used:

Volume = √Area₁ × √Area₂ × √Area₃

Calculation:

Volume = √9 × √25 × √36 cm²

⇒ 3 × 5 × 6 cm²

⇒ 90 cm²

∴ The required volume of cuboid is 90 cm²
