Question

Lead has a density of 11.3 grams/cm cubed. What mass of lead will fit in a 20 cm cubed container?

Answer 1

Use the formula 
D=M/V
Density= Mass divided by Volume
11.3=M/20
You need to get x by itself so you multiply both sides of the equation by 20.
11.3(20)=M/20(20)
226=M

So 226 grams of lead will fit in a 20 cm cubed container.
