What is the amount of water can fill in this tank 2m x 2m 2m.
A person can go to a plane after swimming in a 2M deep pool because the pressure is not too much.
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.
2m by 3m is 64.58 square feet.
