In this video we want to find the density of a piece of metal.
00:02
The density denoted rho is equal to the mass divided by the volume.
00:07
So we're told that the mass is equal to 10 kilograms.
00:10
We want our density in units of grams per centimeter squared.
00:13
So there's a thousand grams in one kilogram to convert.
00:18
So this is 10 times a thousand is 10 ,000 or 10 to the fourth grams.
00:25
Now it displaces two liters of water when it's submerged in the water.
00:30
So that means that the volume is equal to 2 liters.
00:33
That's the same thing as 2 cubic decimeters because 1 liter is 1 decimeter cubed.
00:39
So to convert, there's 10 centimeters in every 1 decimeter and then if we want to square it, we also square the value so this is 2 times 10 to to the second is equal to 200...
