How to Calculate the Volume of a Vessel
- 1). Describe the vessel using the appropriate basic shapes. Basic shapes are cubes, cones, spheres, cylinders, tetrahedral pyramids and prisms. If the vessel is not itself a basic shape, divide it on paper into a set of basic shapes that takes up the same, or close to the same, volume as the vessel itself.
- 2). Calculate the volume of each basic shape. Let's say that your vessel can be closely approximated by the shape of a cube, topped by a cylinder, topped by a cone. Using the basic mathematical formulas -- see "Things You'll Need" -- calculate the volume of the cube, the cylinder and the cone.
- 3). Add the volumes of the various components. In our example, you would add the volume of the cube, the cylinder and the cone to obtain an approximate volume for the vessel as a whole.
