Answer 3

ok well to work out the surface area of each of the horizontal parts you need to identify the number surfaces you have
for the top one:- there is one surface on top. 2 surfaces front and rear, 2 surfaces on the sides, and 2 underneath'

the surface area of this is the same as the bottom part.

the middle part as 2 surfaces front and back and 2 on the sides

top surface has area = 2*5 = 10 cm^2
