### What is Meant by Surface Area of a Rectangular Prism?

In mathematics, a rectangular prism is a three-dimensional figure in which the six faces of the solid are rectangles. A rectangular prism is also called the cuboid. The opposite faces of the rectangular prism are equal in measure, and it has 8 vertices and 12 sides. If “l” is the length, and “h” is the height and “w” is the width of the rectangular prism, the surface area is given by the formula,

The surface area of a rectangular prism = 2 (lw+lh+hw) square units.
