I think first you calculate the area of the triangular face. If you forgot that's ok. The formula is A= bxh divided by 2 which is the same as the area of a triangle is base multiplyed by height and divided by two. Then you need to know the length of the prism(the length of the rectangle)and multiply them together. So your calculation should look like this: Triangular face- A=bxh divided by 2 let's say that the base of the triangle is 5 cm and the height is 12cm Length of prism- let's say the length is 25 cm A=bxh divided by 2 A=5 x 12 divided by 2 A = 20 divided by 2 A = 30 cm squared 30 x 25 = 750cm squared( little 2)

Formula for volume of a triangular prism?
Find the area of a triangular section, 1/2bh, and then multiply by the length of the prism.
Formula for volume of triangular prism?
To find the volume of a triangular prism, find the area of one of the triangles (base of the prism) first (base x height divided by 2). When you have the area of the triangle, then multiply the area of the triangle by the height of the prism, *not the height of the base.
How do you get the volume of a triangular prism?
Like all prisms you find the area of one of the triangular faces and then multiply by the height.
Volume for a triangular prism?
1/2 x length x width x height
What is the formula for finding the volume of a triangular based prism?
Volume = Area of the base X height of prism. This formula works for all prisms, not just triangular prisms. Area of a triangle = height of triangle X 1/2 X base of triangle.
