Explanation:
The formula for finding density is:
Mass/Volume
So for example I have a cube, it has a mass of about 20 grams (not weight) and it's dimensions are about an inchxinchxinch. So basically it is a 20 gram cubic inch cube.
So to find it's density I have to divide mass(=20)/Volume(=1 inch^3). or simplified, 20 ÷ 1 = 20
So the density of my cube is 20..
Hope this helps!
Have a nice day!
