WebA prism has the base that goes through the whole figure, so a triangular prism will have two congruent bases that are a triangle. A triangular pyramid has a triangular base and each base vertex that has an edge that goes to a common vertex. WebAt the beginning of the video, Sal defined that the volume of a pyramid is k (a constant) times the base area times the height. That is no different with the pink pyramid. Sal just integrates the x/2 into (k*y*z*x)/2, which is the same as k*y*z* (x/2) or k*y*z*1/2*x. I hope that helped, and sorry for the later reply.
