We're given a solid s and we're asked to find the volume of this solid.
00:07
We're told the solid is a tetrahedron with three mutually perpendicular faces and three mutually perpendicular edges with lengths three centimeters, four centimeters, and five centimeters.
00:55
This is a pretty complicated exercise.
01:00
It really helps if you have some experience drawing three -dimensional figures.
01:13
So i'll draw a sketch.
01:22
We'll have three axes which are mutually perpendicular.
01:29
So we have an edge with a length of three.
01:45
We also have an edge of length four.
01:52
What is the name is? the reveal was it, the name was gay fucker? it is.
02:00
It's awesome.
02:01
That's what the whole movie built up to.
02:04
And then we also have an edge of length five.
02:11
That was an imprompsy.
02:12
Four -year -old version, he apologized? for him and paul...
02:23
Now to draw the tetrahedron.
02:25
We have these three mutually perpendicular edges with these lengths and three mutually perpendicular faces which are like this i'll call this the x, y, and z axes...
