The area of the cross section times the height of the prism
The area of such a prism is Bh/3, where B is the base area, and h is the height (perpendicular to the plane that contains the base area).The area of such a prism is Bh/3, where B is the base area, and h is the height (perpendicular to the plane that contains the base area).The area of such a prism is Bh/3, where B is the base area, and h is the height (perpendicular to the plane that contains the base area).The area of such a prism is Bh/3, where B is the base area, and h is the height (perpendicular to the plane that contains the base area).
Find the area of one end of the prism, then multiply it by the length of the prism.
It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
