Question 27696
A lake is 120 fathoms deep. Use the fact that there are 6 feet in a fathom to tell the depth of the lake in feet.

The depth of the lake in fathoms is  120 fathoms
Now to find the depth of the lake in feet 
1 fathom = 6 ft
Therefore 120 fathoms = 120X6 feet = 720 feet
Answer: The depth of the lake is 720 feet
Verification: 
Our answer is the depth of the lake is 720 feet 
= (120X6) feet 
= (120)X(6 feet)
= 120 fathoms which is correct.
Real life example:
Your dad gives 120 dollars to buy chocolates for your friends.
And he tells you of a dollar store that sells a pack of 6 chocolates for 1 dollar.
If you  pay 1$ at the store you would get 6 chocolates.
Therefore with 120 $ you will be able to buy (120X6) = 720 chocolates of course, is n't it?
How to verify:
Come home and check the total number of packs.
There sure are 120 packs each having inside it 6 chocolates.
