The formula for the surface area of a triangular prism is SA = bh + (s1 + s2 + s3)H. In this formula, "b" is the triangle base, "h" is the triangle height, "s1," "s2" and "s3" are the three triangle sides, and "H" is the... More »

Multiply the length of each side of the triangle by the depth of the prism separately, then multiply the base of the triangle by its height. Add these four figures together. More »

The formula for the surface area of a triangular prism is SA = bh + (s1 + s2 + s3)H. In this formula, "b" is the triangle base, "h" is the triangle height, "s1," "s2" and "s3" are the three triangle sides, and "H" is the... More »

The volume of a prism is worked out by first calculating the area of the surface and then multiplying that figure by the length of the prism. This applies whatever the shape a prism takes. More »

The formula is the length of the prism times the area of the trapezoid, which is one-half times (a+b) times the height; the area is also called the cross-sectional area. "A" and "B" are the two bases of the trapezoid. Th... More »

The lateral surface area of a cylinder is calculated by multiplying the circumference by the height using the formula 2(pi)(r)(h). The overall overall surface area is calculated by adding the area of each base to the lat... More »
