In this exercise, we're given the density of the lead in grams per cubic centimeter.
00:06
So we have that row, the density, is equal to 11 .3 grams per cubic centimeter.
00:13
And our goal is to find what is the density in kilograms per cubic meter.
00:21
So we need to know some things in order to calculate this.
00:25
First of all, notice that one kilogram is equal to 1 ,000 grams.
00:30
So if we divide both sides by 1 ,000, we obtain that 10 to the minus 3 kilograms is equal to 1 gram.
00:44
So let's keep this in mind.
00:47
Then we also need to know how many cubic centimeters there are in one cubic meter.
00:55
Notice that one cubic meter is equal to 1 times.
01:02
Notice that in each meter we have 100 centimeters.
01:10
So one meter is 100 centimeters and one meter cubed is 100 centimeters cubed...
