<PRE><B>Question 207039</B>
It takes one man one day to dig a 2m x 2m x 2m hole.
 How many days will it take 3 men working at the same rate to dig a 4m x 4m x 4m hole? 
:
From the 1st statement we can say:
1 man/day to dig a hole 2^3 = 8 cu meter hole
:
Let d = no. of days for 3 men to dig a 4^3 = 64 cu meter hole
3d = {{{64/8}}}
3d = 8
d = {{{8/3}}} days for 3 men to dig 4^3 cu/m hole
