Base length (a) 8 mm
Base width (b) 5 mm
Pyramid height (h) 18 mm
What is the volume of the rectangular pyramid?
To calculate the volume of a rectangular pyramid, you can use the formula:
Volume = (1/3) * base area * height
First, calculate the base area using the formula for the area of a rectangle:
Base area = base length * base width
Base area = 8 mm * 5 mm
Base area = 40 mm^2
Now, substitute the values into the formula for the volume of a pyramid:
Volume = (1/3) * 40 mm^2 * 18 mm
Volume = (1/3) * 720 mm^3
Volume = 240 mm^3
Therefore, the volume of the rectangular pyramid is 240 cubic millimeters.
