What is the combined area of the left and right faces of the prism?
There are six surfaces to a prism. There is a front, back, top, bottom, left, and right to every rectangular prism. The surface area of a prism is nothing more than the sum of all the areas of these rectangles.
Top and bottom faces will have equal areas. The front and back faces will have equal areas. Finally, the left and right faces will have equal areas. This means instead of finding the area of all six faces, we only need to find the areas of three faces, multiply each by 2, and then find their sum.
Surface Area = Top + Bottom + Front + Back + Left + Right
Surface Area = 2 x Top + 2 x Front + 2 x Left
Surface Area = 2lw + 2lh + 2wh
So, the answer to the question is – the combined are of left and right faces of prism is – 2wh
