Okay, so in this problem, we must use the archimedes principle because we have a slab of ice.
00:08
And we have a woman standing.
00:12
Let's put a woman in this box.
00:15
So we have the ice floating on water.
00:23
And we must know what should be the volume of the ice.
00:29
So this system is equilibrium and the woman don't get his feet.
00:34
Wet.
00:36
So let's think about.
00:37
First of all, we know that we have the weight of the woman and the weight of this lab of ice.
00:45
And this is an equilibrium because we have a buoyant force in here.
00:52
So let's describe this system using the archimedes principle.
00:57
Let's see.
00:58
We know that the buoyant force is going to be equal the weight, oops, i'm sorry, let's put again, it's going to be equal the weight of the ice plus the weight of the woman.
01:23
So this buoyant force is going to be equal...
