Page 5.1.

So we now can use the view in the previous page to measure the size of the table top, but we don't know the HEIGHT of the table off the floor, to do this we look in at it from the front like is shown below. From this drawing we can see the HEIGHT of the table legs and the thickness of them. Notice in this drawing the floor looks like a red line, because we are looking straight in at it, likewise for the table top, we can see the thickness of the table top here also.
