The answer depends on what information you have about the prism.
To find the volume of a rectangular prism, multiply the length of that prism by the width and height of that prism.
Measure it.
All you have to do is find the area divide it by the base and then you get the height.
Volume of a triangular prism = (1/2.b.h)Hb = base of the triangleh = height of the triangleH = height of the actual prism. = multiplied byThe volume of a prism is volume equals base times height. You have to know the base and height to find the volume.
To find the volume of a rectangular prism, multiply the base, width, and height. If the prism is irregularly shaped, multiply the base and the height.
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.
Volume of rectangular prism = area of base x height
width*height*length=perimeter of a rectangular prism! :)
To find the volume of a triangular prism u have to find the length, width, and height of the prism and then u multiply all of it together
To find the volume on a rectangular prism, the equaton is: length*width*height
You find the volume of a triangular prism by using this formula: Volume = 1/2 base of the triangle x height of the triangle x height of the prism.
