According to cavalieri's principle, if the cross-sectional area of two prisms is the same for every height above the base, then the volumes will be the same. which shape represents the cross-sectional view of these prisms?

A prism is a solid object with flat faces, identical ends and same cross section all along its length.  A cross-section, on the other hand,  is the shape made by cutting straight across an object. Using the Cavalieri's Principle, if the cross-sectional area of two prisms is the same,  for every height above the base, their volumes will be the same. The shape which represents the cross-sectional view of these prisms is a triangle.  

Its a pentagon

Step-by-step explanation:

The Usa TESTPREP picture has a cylinder and the cut comes from the top of the cylinder rendering the answer a pentagon

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
