This pyramid has the same base as the prism, and its height is three times the height of the prism. What is the ratio of the volume of the pyramid to the volume of the prism?

Respuesta :

Volume = area of base x height

Let the height if the prism be x, then the height of the pyramid is 3x.
Volume of pyramid : volume of prism = area * 3x : area * x = 3:1
