The surface area of a prism can be calculated by finding the area of each face and adding them all together.
For this prism, there are two identical rectangular faces with dimensions 6 ft by 3.5 ft, and three rectangular faces with dimensions 8 ft by 3.5 ft.
The area of the two identical faces is 6 ft * 3.5 ft = 21 sq ft each, for a total of 42 sq ft.
The area of the three remaining faces is 8 ft * 3.5 ft = 28 sq ft each, for a total of 84 sq ft.
Adding all the areas together, the total surface area of the prism is 42 sq ft + 84 sq ft = 126 sq ft.
Therefore, the surface area of this prism is 126 square feet.
What is the surface area of this prism? 6 ft 3.5 ft 8 ft
