You'll learn; with the help of several examples and solution, to determine how a change in dimensions affects the volume of solids.
To understand details look into an example: when radius of a sphere is doubled, by what factor the volume will increase, E.g. in a rectangular prism, if the length and width are doubled, then volume increase four times. We'll now work out, what will be the change in volume of a cylinder, if its radius is doubled? You replace r by 2r
in the formula for volume of cylinder,
V = ?r2h
Thus it is concluded that when radius is doubled, volume increases four times.
