The length, breadth and height of a solid cuboid is 20 cm, 16 cm and 12 cm respectively. If cuboid is melted to form identical cubes of side 4 cm, then what will be the number of identical cubes?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 60.
| Understanding/Application |
|
Number of identical cubes formed = ratio of volume of cuboid to volume of cube |
|
Number of identical cubes formed = lbh/a3 = (20 × 16 × 12)/(4 × 4 × 4) = (5 × 4 × 3) = 60 |
