The expression that can be used to find the surface area of the triangular prism is:
2(base area of triangle) + (perimeter of base)(height)
First, we need to find the base area of the triangular prism. Since the base is a triangle, we can use the formula for the area of a triangle:
Area = 1/2 * base * height
Area = 1/2 * 3 * 4
Area = 6 square feet
Next, we need to find the perimeter of the base. The perimeter of a triangle is the sum of all three sides:
Perimeter = 3 + 4 + 5
Perimeter = 12 feet
Finally, we need to find the height of the triangular prism, which is given as 2 feet.
Now we can substitute all the values into the expression:
2(6) + 12(2)
12 + 24
Surface area = 36 square feet
Therefore, the surface area of the triangular prism is 36 square feet.
Which expression can be used to find the surface area of the triangular prism and on the triangular prism we have on the bottom we have 3 feet on the left side. The length is 4 feet on the right side length is 5 feet and on the right side, the bottom is 2 feet, so which expression can be used to find the surface area of the triangular prism?
