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

⇒ V^{2} = (24 × 42 × 28)

⇒ V = 168

⇒ V/14 = 12
