wikiHow Triangular Prism Volume Calculator To calculate the volume of a triangular prism, you need to know the length, width, and height of the prism. The formula for the volume of a triangular prism is: Volume = (1/2 x base x height) x length Here are the steps to find the volume of a triangular prism using a calculator: 1. Enter the length of the prism into your calculator. 2. Enter the base of the triangular base into your calculator. 3. Enter the height of the triangular base into your calculator. 4. Enter the height of the prism into your calculator. 5. Multiply the base and height of the triangular base together. 6. Divide the result by 2. 7. Multiply the result by the length of the prism. For example, let's say you have a triangular prism with a base of 4 cm, height of the base of 6 cm, and a length of 10 cm, and the height of the prism is 8 cm. To find the volume of this triangular prism, you would follow these steps: 1. Enter 10 into your calculator. 2. Enter 4 into your calculator. 3. Enter 6 into your calculator. 4. Enter 8 into your calculator. 5. Multiply the base and height of the triangular base together: 4 x 6 = 24. 6. Divide the result by 2: 24 / 2 = 12. 7. Multiply the result by the length of the prism: 12 x 10 = 120. So the volume of the triangular prism is 120 cubic centimeters. Page
