A lateral surface of a geometric solid is the face the sides.

So what am I measuring?

dogzcatz · Answer

The area of the sides

gottennis121 · Answer

Just the sides and that's it?

mathmale · Answer

"lateral area" means, at least, the area of the sides, not including the area or areas of the ends.  For example, open a can of soup at both ends, discard the top and bottom, and find the area of the sides only.

Or consider the outside area of a house.  Ignore the roof and floor areas.

In this case, they give me height, 26, width 6, and length of 15 as a rectangular prism . So I would do 26 x 15 = 390. Then 390 x 2 since there are two sides at the same measurements. After do 26 x 6 = 156. Then multiple 156 x 2. Add the answer of 390 x 2 and 156 x 2. Am I correct?
