now, the number of chickens are 7*7=49, since there are 7 chickens in each sack and there are 7 sacks.
the number of chicks are 7*7*7=343, since each chicken has 7 chicks, each sack has 7 chickens and there are 7 sacks.
the nubmer of people are 7.
each person has 2 feet, each chicken has 2 feet and each chick has 2 feet.
now total no. of feet= 2*(7+343+49)
=2*399=798
so, there are a total of 798 feet

There are 7 people
There is a total of 7*2 = 14 human feet
Every sack has 7 chickens and every chicken in every sack has 7 chicks.
There are 8 chickens in each chicken family.(One mother and 7 chicks)
There are 7*7 = 49 families (7 mothers to each sack, there are 7 sacks)
There are a total of 49*8 = 392 creatures present
Each has two legs.
There are total of 392*2 = 784 chicken feet.
Total number of feet = 784 + 14 = 798 feet

People's feet= 7 x 2
Chicken's feet= 7 x 7 x 2
Chicks' feet= 7 x 7 x 7 x 2
Total feet
= (7 x 2) + (7 x 7 x 2) + (7 x 7 x 7 x 2)
= (7 x 2)(1 + 7 + ( 7 x 7))
= 14( 8 + 49)
= 14 x 57
= 798

People's feet = 7 x 2 = 14
Chickens feet = 7 x 7 x 2 = 98
Chicks feet = 7 x 7 x 7 x 2 = 686
= 798

First, get the number of people...then get the number of chickens and multiply by it by the number of people...
7(7)=49
Then, get the number of chicks and multiply it by the answer of your previous equation...
49(7) = 343
Multiply this by two since it's asking for the total of feet and not heads...
343 (2) = 686

If you consider a chicken having feet then there are 798 feet present. If you don't consider a chicken having feet then there are 14 feet present.
