Question

"A standard 1 kilogram weight is a cylinder 48.5 mm in height and 44.5 mm in diameter. What is the density of the material in kg/m^3 ?"

I keep trying this problem and it's just a practice problem and the program is telling me the answer is 13300 kg/m^3, but I'd like to see it worked out in full so I can figure it out for myself. My answers are similar so I think I might just be making rounding errors.

Step 1

The density of the material of the cylinder can be calculated using given steps.

Step 2

The density of the material is ratio of mass and volume of the cylinder.

Step 3

Volume of the cylinder can be calc...
