Question: what is the surface area and volume of a triangular prism?
Answer: Again, the formula for volume is 1/2 base of the triangle times the height of the prism, which is the distance between the two bases. ... To recap, to find your surface area we take the lateral area by taking the perimeter of the triangle 10+3+8 times the height of the prism which is 6 and add that to the area of 2 bases.
