#FIND THE SURFACE AREA OF A RECTANGULAR PRISM HOW TO#

Finding the area of the left and right faces: In the above example, w = 5 inches and h = 8 inches, so the front area is 5 inches x 8 inches = 40 square inches. So, the area of the front face = Width * Height, and the back area is the same Width * Height. Go through the previous diagram and see the front face: the one with one edge shown width and another one is shown height. Finding the area of the front and back faces: We have already calculated the top area is 30 square inches. Previously we have already discussed that the top and bottom faces are the same in size. Area of the bottom edge = length * Width.Ĭonsider an example we have mentioned above, the length of the prism is considered as 6 inches and width is 5 inches, so the area of the bottom face is 6 inches x 5 inches = 30 square inches. If you want to calculate the rectangle area, you need to multiply the two edges together. One edge of the rectangle is considered as length, and another one is considered as width. It forms a rectangle shape, just the same as each face. In a rectangular prism, both the left and right faces are the same in size.įinding the surface area of just one face (in our case, bottom).In a rectangular prism, both the front and back faces are the same in size.In a rectangular prism, both the top and bottom faces are the same in size.

To cover the whole surface area, you need to consider six different 'faces.' The large size of the base is 6 inches, so the length = 6, w = 5, and h = 8 Let's understand this concept with the help of an example.Ĭonsider an empty box that has a base has base that measures 5 inches by 6 inches, and it stands 8 inches tall.

If you are unable to decide the side, represent the three-line that meets at that corner. The given figure depicts the diagram of a rectangular prism with length l, width w, and height h located next to the three different edges of the shape.

In this article, we will learn how to find the surface area of the rectangular prism. The six sides come in 3 pairs of parallel sides. A rectangular prism refers to a 3-Dimensional object with six sides that are rectangles.
