what is the volume of the rectangular pyrimid? length, 8mm width, 5mm altitude, 18mm
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 base area of the pyramid. Since it is a rectangular pyramid, the base is a rectangle. To find the area of a rectangle, you multiply the length and width:
Base area = length * width
Base area = 8mm * 5mm
Base area = 40mm^2
Now, you can calculate the volume of the pyramid:
Volume = (1/3) * 40mm^2 * 18mm
Volume = (1/3) * 720mm^3
Volume = 240mm^3
Therefore, the volume of the rectangular pyramid is 240 cubic millimeters.
