The areas of three consecutive faces of a cuboid are 12 cm², 20 cm² and 15 cm2, then the volume (in cm³) of the cuboid is
-
- 3600
- 100
- 80
- 60
- 3600
Correct Option: D
Let the length, breadth and height of the cuboid be x, y and z cm respectively, then
xy = 12 ; yz = 20 ; zx = 15
∴ x²y²z² = 12 × 20 × 15 = 3600 cm6
∴ v = xyz = √3600 = 60cm³
