Cuboid whose length = l, width = w and height = h

To find the volume of a cuboid, multiply its length by its width by its height. This can be written as: v o l u m e = l × w × h.


Sphere whose radius = rr

Volume of sphere =43πr3\dfrac{4}{3}\pi r^3


Cone having height = hh , radius = rr and slant height = ll

Volume of cone =13πr2h\dfrac{1}{3}\pi r^2h


The general formula for calculating the volume of any prism is:

Volume = (Area of the base) ×\times length

For a triangular prism, the formula would be:

Volume = (Area of the triangular base) ×\times length 


Cylinder whose radius = rr , height = hh

Volume of cylinder =πr2h\pi r^2 h
