Question

Find the total surface area of the net below

Answer 1

75

Explanation:

for the square in the middle, 7x4=28

for the triangles on the left and right 7x5=35 and since there are two of them you dont need to divide by 2

for the triangles on top and bottom, 3x4=12 and also 2 of them so you dont need to divide by 2

then just add it all up
