What's the surface area of the triangular prisim

1 answer

To find the surface area of a triangular prism, you need to calculate the area of all the surfaces that make up the prism.

First, calculate the area of the triangular base. The formula for the area of a triangle is 1/2 * base * height. Let's say the base of the triangle is 6 units and the height is 4 units. The area of the triangular base would be 1/2 * 6 * 4 = 12 square units.

Next, calculate the area of each of the three rectangular sides. The formula for the area of a rectangle is length * width. Let's say the length of the prism is 8 units and the width is 4 units. The area of each rectangular side would be 8 * 4 = 32 square units. Since there are three sides, the total area of the three rectangular sides would be 3 * 32 = 96 square units.

Finally, add the area of the triangular base to the total area of the three rectangular sides to get the surface area of the triangular prism. 12 + 96 = 108 square units.

Therefore, the surface area of the triangular prism is 108 square units.
