To calculate the surface area of the prism, you need to find the area of all six sides and then add them together.
1. The top and bottom faces are rectangles with dimensions 6 ft by 3.5 ft. The area of each rectangle is 6 ft x 3.5 ft = 21 ft2. Since there are two of these faces, the total area for the top and bottom faces is 2 x 21 ft2 = 42 ft2.
2. The front and back faces are also rectangles with dimensions 6 ft by 8 ft. The area of each rectangle is 6 ft x 8 ft = 48 ft2. Since there are two of these faces, the total area for the front and back faces is 2 x 48 ft2 = 96 ft2.
3. The left and right faces are also rectangles with dimensions 8 ft by 3.5 ft. The area of each rectangle is 8 ft x 3.5 ft = 28 ft2. Since there are two of these faces, the total area for the left and right faces is 2 x 28 ft2 = 56 ft2.
Adding all the areas together: 42 ft2 + 96 ft2 + 56 ft2 = 194 ft2
Therefore, the surface area of this prism is 194 ft2.
