ONE THIRD of the area of the base, B, times the height, h Calculate the Volume of Pyramids (or cones):   Pay close attention to the shape of the base! 1. 2. ONE THIRD of the area of the base, B, times the height, h

3. The base of a pyramid is a square. The side length of the square is 12 inches. The height of the pyramid is 5 inches. Find the volume of the pyramid.   4. The Great Pyramid of Khufu in Egypt is no longer smooth on the exterior and is NOT completely solid. If it were smooth and solid, calculate the volume of the pyramid, given the following dimensions: height = 146.71 m, square base with side length 230.348m.
