How do you find volume of a triangular prism?
How do you find the volume of a rectangular prism relates to the volume of a tringular prism if the two have the same lengthwidthand height?
The volume of a rectangular prism is found by; Volume = Length x Width x Height The volume of a triangular prism is found by; Volume = 1/2 x Length x Width x Height Therefore, Length, Width and Height being identical, 1) the volume of a rectangular prism is twice that of a similar triangular prism OR 2) the colume of a triangular prism is half that of a similar rectangular prism.
Multiply the length of the prism by the area of the triangular face. How you find the area of the triangular face will depend on what information you have about the triangle: 3 sides, 2 sides and the included angle, 1 side and 2 angles, base and vertical height or any of a number of other sets of data.
