There is no dirt in a hole. Only air.
Good one.

There is no soil, it's a hole.
None. By definition a hole is an empty space.
The volume of the hole is 3m x 2m x 2m = 12 cubic meters. To convert to cubic centimeters, you would multiply by 1,000,000 (1 cubic meter = 1,000,000 cubic centimeters). So, the volume of the hole in cubic centimeters is 12,000,000 cubic centimeters.
NONE! The hole does have a volume of 3 x 2 x 2 = 12 cubic meters. 1 cubic meter is equal to 1,000,000 cubic centimeters. So you could FILL THE HOLE with 12,000,000 cubic centimeters of soil.
200cm = 2m
1m-2m
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.
A person can go to a plane after swimming in a 2M deep pool because the pressure is not too much.
