Closeup on a person's hand holding the tip of a transparent blue pyramid. Caption. Has 4 triangular sides, and a square base.

Explains how the formula is developed for calculating the surface area of geometric solids (three-dimensional) shapes, such as right prisms: rectangular, triangular, and circular (cylinder). Also explains how to calculate surface area of non-right prisms, such as: four-sided pyramids, cones, and spheres. Uses formulas for the area of two-dimensional shapes learned in Geometry, Part 1 (#11549) to calculate the total surface area.
