Lesson Description:

Students learn that the formula for the volume of a prism is length times width times height, so the volume of a prism that has a length of 25 inches, a width of 4 inches, and a height of 9 inches, is 25 times 4 times 9, or 900 cubic inches. Students also learn that the formula for the volume of a cube is side length cubed, and the formula for the volume of a pyramid is 1/3 times the area of the base times the height of the pyramid. Students are then asked to find the volume of prisms, cubes, and pyramids.
