Let’s imagine you are tiling a swimming pool (or some kind of box) and want to know how much tile you will need. Surface Area of a Rectangular Prism The total region or area covered by all the faces of a rectangular prism is defined as the surface area of a rectangular prism.

The bottom has the same area, so the area of the two together is 2 times 30 = 60. Surface Area of a Rectangular Prism Calculator Example. The top has a length of 6 and a width of 5, so its area is 6 X 5 = 30.

The area of the two together is 2 times 24 = 48. (In the diagram, you can’t see the side on the left.) Each of those sides measures 6 x 4, so each one’s area is 24.

Now consider the sides on the left and right. Introduction rectangular prism with base and lateral faces labeled A prism is a 3-dimensional figure that has two parallel, congruent bases connected by.

There is an identical piece in the back with the same area the area of the two together is 2 times 20 = 40. We have been working on volume in my high school equivalency class, but we haven’t discussed surface area yet. You can use this formula for any rectangular prism, and you will always get the surface area. Add them all together to get the area of the whole shape: lw + lw + wh + wh + lh + lh.
