7-2 objectives: find the surface area of a right prism. find the volume of a right prism. Cavalieri's Principale, use this to find the volume and surface area of a right or oblique prism. Surface Area of a right Prism S= L +2B or S= hp+2B Volume of a Prism V= Bh Cavalieri's Principle If two objects have an equal height, then, they have and equal area, and a equal volume. example: find the surace area and volume of a hexagonal prism, with a height of 48in, perimeter of 84in, and a base of 14in. Surface Area S= hp+ 2B S= 48x84+2x14 =56,476 units² Volume V=Bh V=14x48 =672 units³
