Answer:The answer is
Yes
A total of 1/40 of a foot is needed if spaced with wall.
A total of 1/24 is needed if the desks touch the wall with equal spacing in-between the desks.
Explanation:
If you divide 24 5/8 with 6 1/8 then you can get at least 4 meaning that you can fit the four office desks.
For the spacing you would divide 1/8 by three to get 1/24.
1/24 is the spacing in-between the office desks while the desks touch the wall. If it also contains the walls then you would divide by 5 to get 1/40
