    Question

    The base of a prism is a triangle with sides 9 cm, 12

    cm, and 15 cm, and its height is 20 cm. Find the volume of the prism.
    A 540 cm³ Correct Answer Incorrect Answer
    B 1080 cm³ Correct Answer Incorrect Answer
    C 1350 cm³ Correct Answer Incorrect Answer
    D 1440 cm³ Correct Answer Incorrect Answer

    Solution

    The base is a right triangle (9² + 12² = 15²). Area of the base = (1/2) × base × height = (1/2) × 9 × 12 = 54 cm². Volume = base area × height = 54 × 20 = 1080 cm³.
