WebDec 14, 2015 · To calculate the volume of the Milky Way, we assume that it can be approximated by a disk with a thickness of 1000 light years and a radius of 50,000 light years. A light year is about 9.5 x 10^ (12) km, while the volume of a disk is pi* (thickness)* (radius)^2. Plugging in our thickness and radius we get about 6.7 X 10^ (51) km^3.
