Question
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)
cm3
81 cm³
To find the volume of a rectangular pyramid, you can use the formula V = (1/3) * base area * height. Since the base is a rectangle, the base area is 4 cm * 9 cm = 36 cm².
Plugging in the values from the problem, we get V = (1/3) * 36 cm² * 21 cm = 252 cm³.
Therefore, the volume of the slice of cheese is 252 cm³.
