Volume is all about how much space a object occupies. It depends on size and shape of the object. There are various geometrical objects like cube, prism, cuboid, cylinder etc. Each has the volume different from the other.
Cube is that which has six sided squares faces whereas cuboid is that which has six sided rectangular faces.The ellipsoid is that having its planes as ellipses or the circles. Torus is the spherical geometrical figure having single hole. Here each geometrical body has the different shape compared to other as shown in figure below. Depending on that its volume also varies.
Here are below given some volume calculators for cube, cuboid, Ellipsoid and torus etc. you just can click on the link below to get the calculator which you desire.
