Answer:
It would get <u>20</u> complete turns.
Step-by-step explanation:
Given:
The lead of a screw is the distance that the screw advances in a straight line when the screw is turned 1 complete turn. If a screw is 2 1/2 inches long and has a lead of 1/8 inch,
Now, to find complete turns.
Length of screw = 
Lead of screw = 
As, given the screw advances in a straight line when the screw is turned 1 complete turn.
Now, to get the number of complete turns it would divide length of screw by lead of screw:

Therefore, it would get 20 complete turns.
Volume= length times width times height
