A slice of cheese is cut from a wheel of Parmesan and the wedge approximates the shape of a rectangular pyramid. Its base is 4cm wide and 9cm long and 21cm tall, what is the volume

Answer 1

To find the volume of a rectangular pyramid, you can use the formula:

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

First, you need to find the area of the base:

Area = length * width
Area = 9cm * 4cm = 36 cm²

Now you can plug the values into the formula:

Volume = (1/3) * 36cm² * 21cm
Volume = (1/3) * 756cm³
Volume = 252cm³

Therefore, the volume of the cheese wedge is 252 cubic centimeters.
