The volume of a rectangular pyramid is given by the formula V = (1/3) * base area * height.
First, we need to find the area of the base of the pyramid:
Base area = 4 cm * 9 cm = 36 cm^2
Now, we can plug the values into the formula:
V = (1/3) * 36 cm^2 * 21 cm
V = 252 cm^3
Therefore, the volume of the piece of cheese is 252 cm^3.
