    Question

    A cuboid has dimensions 12 cm, 8 cm, and 6 cm. If all

    the dimensions are increased by 50%, what will be the percentage increase in the volume of the cuboid?
    A 237.5% Correct Answer Incorrect Answer
    B 300% Correct Answer Incorrect Answer
    C 275% Correct Answer Incorrect Answer
    D 225% Correct Answer Incorrect Answer

    Solution

    Original volume = 12 * 8 * 6 = 576 cubic cm. New dimensions: 1.5 * 12 = 18 cm, 1.5 * 8 = 12 cm, 1.5 * 6 = 9 cm. New volume = 18 * 12 * 9 = 1944 cubic cm. Percentage increase in volume = [(1944 - 576) / 576] * 100 = (1368 / 576) * 100 ≈ 237.5%.
