It takes one man one day to dig a 2m x 2m x 2m hole How long does it take 3 men working at the same rate to dig a 4m x 4m x 4m hole?
The rate for one man to finish a 2mx2mx2m whole is...
1 man = 8m3 per day
At the same rate three men can each do a 2mx2mx2m whole. This is how much they altogether can do in one day.
3 men = 24m3 per day
The whole they have to dig is this size.
4mx4mx4m which is 64m3
Since three men can do 24m3 per day it will take them 2 days and 16 hours to dig a 64m3 hole.

Assuming they can work in parallel, the answer should be 5. 5 men produce 1 hole per hour in the first example. At that rate, they produce 5 holes in 5 hours. The same 5 men, working at one hole per hour, should be able to produce 100 holes in 100 hours (assuming they don't need sleep, etc.)
