To find the surface area of a rectangular prism, find its length, width and height. Multiply width times height, length times width, and length times height. Add the three products together, and multiply the sum by two. ... More »

The difference between a rectangular prism and a cubic prism is in the equality of the faces of the prism. All sides of a cubic prism are equal, while a rectangular prism's sides have different measurements. More »

Rectangular prisms have eight vertices. They also have six faces and 12 edges. "Vertices" is the plural of "vertex," which is defined as the point where three or more faces come together to form a point or a corner, in t... More »
