A metallic solid cuboid of dimensions 36 cm × 18 cm × 12 cm is melted and recast in the form of cubes of side 6 cm. Find the number of cubes so formed.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 36
Concept used:
Volume of cuboid = n × volume of cube
L × B × H = n × side3 ---- (1)
Where, n = number of cubes
Calculations:
Using equation (1), we get
⇒ 36 × 18 × 12 = n × 6 × 6 × 6
⇒ n = 12 × 3 = 36
