What is the volume of the rectangular pyramid? with 18mm 8mm and 5mm

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

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

First, calculate the area of the base of the rectangular pyramid:

Base area = length * width
Base area = 18mm * 8mm
Base area = 144 mm²

Then, calculate the volume of the rectangular pyramid:

Volume = (1/3) * 144 mm² * 5mm
Volume = 1/3 * 720 mm³
Volume = 240 mm³

Therefore, the volume of the rectangular pyramid is 240 cubic millimeters.
