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 »

A rectangular prism's formula is given as length (l) multiplied by the width (w) and height (h), or with the formula V = l * w * h. A rectangular prism is a three-dimensional figure that has six rectangular faces, and al... More »

A prism is a three-dimensional figure made of two equivalent parallel faces and rectangular faces that connect them. To find the volume of a prism, find the area of one of the parallel faces, and multiply by the perpendi... More »

A cuboid has its own surface area and volume, and it is a three-dimensional solid plane figure containing six rectangular faces, eight vertices and twelve edges, which intersect at right angles. It is also referred to as... More »

To find the volume of a triangular prism, multiply the base area by the length of the prism. You need to know the base area and the length of the prism. Use a ruler, a pen, a divider, a piece of paper and a calculator. 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 »

Calculate the surface area of a triangular prism using the formula (b x h) + (S1 + S2 + S3) H. You need the value of "b," or base of the triangle, "h," or height of the triangle, S1, S2, S3 or sides of the triangle, and ... More »
