What is the volume of the rectangular pyramid? 18mm, 8mm, and 5 mm?
To find the volume of a rectangular pyramid, you can use the formula:
Volume = (1/3) * base area * height
The base area of a rectangular pyramid is the area of the base rectangle, which is length times width. In this case, the base rectangle has dimensions of 18mm by 8mm.
Base area = 18mm * 8mm = 144mm^2
Now, the height of the pyramid is given as 5mm.
Volume = (1/3) * 144mm^2 * 5mm
Volume = (1/3) * 720mm^3
Volume = 240mm^3
Therefore, the volume of the rectangular pyramid is 240 cubic millimeters.
