    66.7 in^3

    Step-by-step explanation:

    The volume of a triangular pyramid is given by

    V = 1/3 B h

    where B is the area of the base and h is the height

    Calculate the area of the base. The base is a triangle

    B = 1/2 bh where b is 8 and h is 5

    = 1/2 (8) * 5

    =20

    V = 1/3 (20) 10

    66.6666666

    To the nearest tenth

    66.7 in^3

    66.7 in³

    Step-by-step explanation:

    Volume = ⅓ base area * height

    = ⅓ (½ * 5 * 8) * 10

    = ⅓ * 20 * 10

    = 200/3 in³

    = 66.6667 in³
