So in this question, they say a cube is located such that its top four corners.
00:05
Have coordinates 173, 113, 713, 713, and 773.
00:13
I want to give the coordinates of the center of the cube.
00:17
So let's think about this.
00:19
Let's look at the cube and look at its top.
00:25
So the top of the cube is in the plane z equals 3.
00:32
So in the plane z equals three, what do we have? we've got one seven, we've got one seven, we've got one seven, we've got one one, we've got seven, we've got seven one, we've got seven one, and we have seven.
00:55
So this is the top of the cube in the plane z equals three.

This guy is a square that is six by six.
01:07
And so where is the center of this square, which is the top face of the cube? well, the center of the square that is the top face of the cube would have an x -coordinate of four and a y -cordinate of four...
