You have 4 triangles with Height = 3mm and base = 8 mm and 5 rectangles with base= 8mm and height=2mm Do you know the area of a triangle with respect to base and height? ditto with rectangles?

its easy you can do it, it is sum of surface areas

Triangle area is 0.5 B H so (3)(8) = 24 mm squared but there are 4 so (24)(4) mm squared for the roof. For rectangles area is BH so (8)(2) = 16 but we have 4 so (16)(4) the total surface area would be then the sum from the roof and the sides or (24)(4) + (16)(4) = (38)(4) = 152 mm squared

it's 4*(8*2)+(8*8)+4(2*1/2*4*3)

forgot the halves in the triangle calculation. Triangle area is 0.5 B H so 0.5(3)(8) = 12 mm squared but there are 4 so (12)(4) mm squared for the roof. For rectangles area is BH so (8)(2) = 16 but we have 4 so (16)(4) the total surface area would be then the sum from the roof and the sides or (12)(4) + (16)(4) = (28)(4) = 112 mm squared plus 64 for the bottom to get 176 mm squared
