A slice of cheese is cut from a wheel of parmesan, and the wedge approximates the shape of a rectangular pyramid. Its base is 4 cm wide and 9 cm long. The wedge is 21 cm tall. What is the volume of the piece of cheese?(1 point)
The volume of a rectangular pyramid is given by the formula V = (1/3)bh, where b is the base area and h is the height.
In this case, the base area is 4 cm x 9 cm = 36 cm^2 and the height is 21 cm.
So, V = (1/3)(36 cm^2)(21 cm) = 252 cm^3
Therefore, the volume of the piece of cheese is 252 cubic cm.
