Find the lateral area of the prism. Round your answer to the nearest whole number. The bases are the large 13 x 4 rectangles. https://www.connexus.com/content/media/461958-3232011-35122-PM-1691221172/res00000/ppg/examview/S_GEOMB_05_Unit_Test/mc003-1.jpg
The lateral area would be 13*4- that's for one lateral face, but because this is 3D and there are 2 lateral faces, you's multiply your product by 2
13*4=52 2 sets of 52= 104
those are my answers 68 m2 156 m2 120 m2 172 m2
If those are your only choices, then I'm confused. Wait- is lateral area in your school the same thing as surface area?
Like if you were going to wrap a box with wrapping paper, would the amount of paper you used be lateral area?
If so, then it would be 172. But I'm not sure if that's what your teacher means.
