The length, breadth and height of a solid cuboid is 14 cm, 12 cm and 8 cm respectively. If cuboid is melted to form identical cubes of side 2 cm, then what will be the number of identical cubes?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 168
If a shape is melted to any any other shape , their volume remains always same.
Volume of cuboid = Length × Breadth × Height
Volume of cube = Side3
The length, breadth and height of a solid cuboid is 14 cm, 12 cm and 8 cm (Given)
Volume of Cuboid = 14 × 12 × 8 = 1344
Volume of Cube = 23 = 8
No. of cubes = 1344/8 = 168.
