The volume of a triangular prism can be found by multiplying the base times the height. Both of the pictures of the Triangular prisms below illustrate the same formula. The formula, in general, is the area of the base (the red triangle in the picture on the left) times the height,h. read more
To calculate the volume of a triangular prism, measure the base and height of either one of the triangular bases. Multiply the base by the height, stating your answer in square units, then divide the result by 2. Next, measure the length of the prism and multiply this by the previous figure to get the volume. State your answer in cubic units. read more
