Question

The area of three adjacent faces of a cuboid are 24 cm², 42 cm² and 28 cm² and the volume is V, then, the value of V/14 is – 

1. 10
2. 15
3. 18
4. 12

Answer 1

Correct Answer - Option 4 : 12

Given:

Let the length, breadth and height of a cuboid is l, b and h, then, the area of the three adjacent faces will be –

⇒ lb = 24, bh = 42 and lh = 28

Formula used:

Volume of a cuboid = lbh

Calculation:

⇒ lb × bh × lh = 24 × 42 × 28

⇒ V² = (24 × 42 × 28)

⇒ V = 168

⇒ V/14 = 12
