Mass is defined as how much matter comprises an object. Mass, despite its International System of Units measure of kilograms, is often confused with weight, which is the gravitational attraction between an object and the Earth. Mass is calculated as the
1. Calculate Volume of a Cube Calculate the volume of a rectangular solid using the formula \(V=l\times w\times h\) Begin by multiplying length × width × height. So if your cube is 5 cm long, 3 cm wide and 2 cm tall, its volume is 5 × 3 × 2 = 30 cubic centimeters. ...

Answer to: Calculate the volume of a CD that is 0.75\ \rm{mm} thick has outer diameter of 128\ \rm{mm} and inner diameter of 15\ \rm{mm}. By...
Now I have a similar problem again. I have to calculate a volume of a hole inside a 3D body. This I have to calculate at each time step. My approach was to do the same as in the previous problem: use the divergence theorem with a suitable vector function. ...
The equation to calculate density is represented with the formula density = mass / volume. To determine the density of a solid that has regular side lengths, it is first needed to calculate the volume of the solid using the equation volume = length x width x height. Once the volume is ...
