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?
