A box with dimensions 15 cm × 12 cm × 10 cm is completely filled with cubes of side 1 cm. How many cubes are used?
Show answer & explanation
Correct answer: A
Explanation
Dimensions of the box = 15 cm, 12 cm, 10 cm
Side of the small cube = 1 cm
Number of cubes = (l × b × h) / (Volume of the small cube)
Volume of the box = 15 × 12 × 10 = 1800
Volume of the small cube = 1³ = 1
Number of cubes = 1800 / 1 = 1800
