Question

I don't know to solve the surface area of the prism

Answer 1

12.4 is the surface area, why? because 3 x 1 is 3, 2 x 2.2 is 4.4 for the triangles because the total amount of what you get for a triangle just split it in two so, and for the bigger rectangle 2 x 3 is 5 so add all of that together so 3 + 4.4 + 5

I beg you to mark me a brainiest please
Also I hope that helped

Answer 2

(1ft x 1ft) + (3ft x 3ft) = 7sqft
