Answer:
28
Step-by-step explanation:
To find the area of a rectangle we multiply two edges together.
since we are looking for the surface area we are actually going to be finding 6 different areas and adding them together (since there are 6 sides to a rectangle)
ok so sides 1 and 2, the edges on the left and right will be equal, and then the four sides in the middle are all going to be equal
2(1x2) + 4(3x2) = 4 + 24 = 28
41-28=13 questions, but you also have to do 41 and 28, so 15 questions
