Find the volume of rectangular pyramid that has a base of 3 x 4in and an altitude of 6 in. Can you do it like a bad at math 7th grader did it.
Ok, so first we gotta find the area of the base. That's easy, it's just length times width, so 3 x 4 = 12 square inches.
Now, to find the volume, you gotta use the formula 1/3 x base area x height. The height is the altitude, so that's 6 inches.
So, plug in the numbers: 1/3 x 12 x 6 = 24 cubic inches.
So, the volume of the rectangular pyramid is 24 cubic inches.
