If a square-based prism and a square-based pyramid have the same height, and the same base area, how do their volumes compare?

V(pyramid) = 1/3 BASE AREA times height
the base edge is 20 and the slant height is 26, find the volume of the square pyramid
the base is a right triangle with lengths 7, 24, 25. The altitude of the pyramid is 30. Find the volume.

h= 19. The base edge is 8. Find the
volume and the surface area. (round to
nearest hundredth)
The area of one lateral face of the regular hexogonal pyramid is 24 3
The base edge is 4. Find the volume and the surface area of the pyramid in
exact form.

60 degreesradius is 10 . Find the volume and the surface area.
Suppose you roll the figure into a cone. If the open angle is 135 degrees and the length
marked x is 12, What would the volume and surface area be?
x
1350
