From a cuboid of dimension 10 cm × 5 cm × 2.5 cm, small cubes of edge 2.5 cm are cut. How many small cubes are formed from the cuboid?
Show answer & explanation
Correct answer: B
Explanation
Volume of the cuboid = 10 × 5 × 2.5 = 125 cubic cm
Volume of the small cube = 2.5 × 2.5 × 2.5 = 15.625 cubic cm
Number of small cubes = 125 ÷ 15.625 = 8
