Math problems involving 3-dimensional shapes may require you to find the lateral surface area of a square pyramid. The lateral surface area is the sum of the areas of its lateral faces (sides), while the total surface area is the sum of its lateral faces and its base.

The lateral area of a pyramid is the total surface area of the pyramid excluding the base. The formula for the lateral area of a regular pyramid is half the slant height multiplied by the perimeter. If the pyramid is irregular, calculation of the lateral area involves more complex equations and depends on the shape of the base.

A huge collection of surface area worksheets contain rectangular prism, cone, cylinder, sphere and other prisms and pyramids. ... It broadly classified as surface area of prisms, cylinders, pyramids and spheres. Though the cone is a pyramid, we placed it under separate segment for easy identification. ... Find the lateral surface area of a ...

For a rectangular pyramid (which is not a square bottom) you can not use the standard formula of Surface Area = B + 1/2 * P * s, because there is more than one slant height.
