Aim: How do we find surface area and lateral area of prisms and cylinders?

A faster way to find lateral area:

L.A = ph

Surface area = lateral area + area of the bases
 ( S.A = L.A + 2B)

The surface area of a prism = 2 × area of base  +  perimeter of base × H

The actual formula used to find the surface area will depend on the shape of the base of the prism.
