In both cases,
volume = cross-sectional area x length
The formula for finding the volume for a triangular pyramid is half base x height x length. A triangular pyramid has four faces.
The volume of a rectangular prism can be found by the formula: volume=length*width*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.
The rectangular prism has a rectangular cross-section; the triangular prism has a triangular cross-section. Any other difference would be related to this fact - for example, differences in the formulae for the surface area, for the volume, etc.
for both of them its... volume=length times width time height and its always cubed.
The formula to find the volume of a object or container in cc (cubic centimeters) depends on its shape. Different formulae are used for spherical, triangular, rectangular, cylindrical, etc. shapes. There is no formula for finding the volume of irregular shapes.
A triangular prism can be thought of as a stack of triangles. Then the volume is equal to the area of the triangular base multiplied by the height of the prism, or 1/2 length * width * height.
The base area * height = Volume
Volume = (length) times (width) x (height)
Volume of a prism and a cylinder= cross-section area*height or length
It is 1/3*(base area)*(vertical height).
Volume for a rectangular or square prism= length x height x width
