00:01
All right, we are starting out by filling in this column.
00:09
One cahis, one finega, one quartia, one al -mude, and one me -deo.
00:34
Okay, what's interesting is that we've got one, one, one, one, one.
00:39
One across the diagonals.
00:44
What we need to write down below is just the reciprocal of what's above the diagonal.
00:54
So i'm putting in what's above the diagonals right now.
01:04
Okay, so here we just need to write 112.
01:10
Here we just have to write 148.
01:14
Here we just write one -fourth.
01:18
After one -fourth is one -third, one -half.
01:23
So you see how we're just writing reciprocals? one -twelfth, one -sixth, one over 144, one over 244, one over 288.
01:42
Okay.
01:43
Now, express seven almudes as medeos.
01:57
Well, one almud is two medeos.
02:09
Cancel out the almuds and you get 14 medio.
02:16
Okay, so we need to express that as that.
02:20
Also as kheises.
02:30
So where's khees is? one k -his is 144 al -mudes.
02:47
Okay.
02:48
So that would be 7 over 144 of a k -his.
02:59
Okay, i've run out of room, so i'm going to go up here.
03:06
Seven al -mudes, and now we need to go to a cubic centimeters...
