Calculate the surface area of a right triangular prism with dimensions w =12in .L =18in. and h =8in . How many square inches is the surface area
The surface area of a right triangular prism can be calculated by finding the area of each face and summing them up.
The triangular faces have dimensions w = 12in, L = 18in, and h = 8in.
The area of one triangular face is (1/2) * w * L, which is (1/2) * 12in * 18in = 108in².
Since there are two triangular faces, their combined area is 2 * 108in² = 216in².
The rectangular faces have dimensions w = 12in, L = 18in, and h = 8in.
The area of one rectangular face is w * h, which is 12in * 8in = 96in².
Since there are two rectangular faces, their combined area is 2 * 96in² = 192in².
In total, the surface area of the right triangular prism is 216in² + 192in² = 408in².
Therefore, the surface area of the right triangular prism is 408 square inches.
