Google but I know what you are a slice of cheese is cut from a wheel of Parmesan and the wedge approximates the shape of a rectangular pyramid it's base is 4 cm wide and 9 cm long the wedge is 21 cm tall what is the volume of the piece of cheese

To find the volume of the piece of cheese, we first need to calculate the volume of the rectangular pyramid.

The volume of a rectangular pyramid is given by the formula:

Volume = (1/3) * base area * height

The base area of the wedge can be calculated as:

Base area = length * width
Base area = 9 cm * 4 cm
Base area = 36 cm^2

Now, we can calculate the volume of the wedge:

Volume = (1/3) * 36 cm^2 * 21 cm
Volume = (1/3) * 756 cm^3
Volume = 252 cm^3

Therefore, the volume of the piece of cheese is 252 cubic centimeters (cm^3).
