if the volume of the pyramid is 280 what would the volume of the prism be?

To determine the volume of the prism, we need to know the dimensions of the pyramid and the prism. Since the volume of a pyramid is typically calculated as (1/3)*Base Area*Height, we need to determine the base area and height of the pyramid.

Let's assume the base area of the pyramid is 40 and the height is 21.
Volume of pyramid = (1/3)*40*21 = 280

Now, if the prism has the same dimensions as the pyramid, the volume of the prism would be calculated as Base Area*Height = 40*21 = 840.

So, the volume of the prism would be 840.
