We can generalize the relationship between the volume of cubes and pyramids to prisms and pyramids.[br]For the volume of a prism we know the formula: [br][b]V[sub]prism[/sub] = area[sub]base[/sub] . height[/b] [br]The volume of a pyramid equals 1/3th of the volume of the prism with the same base and height as the pyramid. We can conclude:[br][b]V[sub]pyramid[/sub] = 1/3 . area[sub]base[/sub] . height[/b][br]
