What is the surface area and volume? explain in detail how to solve.

The surface area is the sum of the area of all the faces of an object.

Area of bottom face: 4×2.5=10

Area of right and left sides: 2(2.5×2)=10

Area of front and back sides: 2(4×2)=16

Area of the rectangular sides of the roof: 2(2.5×2.5)=12.5

Area of the triangle sides of the roof: 2(1/2(4×1.5))=6

Add up all of these to get 54.5 yd^2

29 mil
