The volume of any prism can be found by calculating the area of the base and multiplying it by the height of the prism. Recall that a prism is a solid shape composed of a base that is a polygon. By translating that base "up" and adding the "sides" to create the solid shape, you have constructed the prism. And now you can calculate its volume.
Note that the base could be triangular, or could be a square, a pentagon, hexagon, or any other polygon. Standard rules apply for calculating the areas of these polygons.

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.
The volume of any prism is worked out in the same way whether it's a hexagonal prism, circular prism or a triangular prism. You just need to times the length of the prism against the area of the cross-section.
V = base area × height
Mass = Density x Volume
The answer depends on what measurements you do have.
