Let d represent number of days and n represent number of workers.
We have been given that when building a house, the number of days required to build varies inversely with with the number of workers.
We know that the equation
represents the relation where y is inversely proportional to x and k is the constant of proportionality.
So our required equation would be 
Upon substituting our given values, we will get:



Since constant of proportionality is 665, so our equation would be
.
To find the number of days it will take to build a similar house with 5 workers, we will substitute
in our equation as:


Therefore, it will take 133 days for 5 workers to build a similar house.

The rule that represents those numbers is .....idk
I think the answer might be <em>B 30.4 ft</em> if it not it might be <em>C 161 ft</em>
pls correct me if i'm wrong sorry if the answers is wrong
512x^3 would be the answer
