The volume of a pyramid varies jointly as its height and the area of its base. A pyramid with a height of 12 feet and a base with area of 23 square feet has a volume of 92 cubic feet. Find the volume of a pyramid with a height of 17 and a base with an area of 27 square feet.

• HELP!!! Math -

v = kha

92 = k(12)(23)

92 = 276k

k = 92/276 = 1/3

v = 1/3ha

v = (1/3)(17)(27)

v = 153
