A solid cuboid with dimensions 2 m × 4 m × 10 m is melted to form small solid cubes of side 8 cm. How many such cubes can be formed?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 156,250.
Cuboid dimensions: 2 m × 4 m × 10 m
Convert to cm: 200 cm × 400 cm × 1000 cm
Volume of cuboid = 200 × 400 × 1000 = 80,000,000 cm³
Volume of one cube = 8 × 8 × 8 = 512 cm³
Number of cubes = 80,000,000 ÷ 512 = 156,250
