What weight would a roll of wire be if 1/2 pound is the weight for 4 feet?

To determine the weight of the roll of wire, we first need to establish how much wire is represented by 1/2 pound. The question states that 1/2 pound corresponds to 4 feet of wire.

To find the weight for a longer length, we can calculate the weight per foot. Since 1/2 pound corresponds to 4 feet, we can divide the weight by the length to find the weight per foot:

Weight per foot = (1/2 pound) / 4 feet = 1/8 pound per foot.

Next, to figure out how much a full roll of that wire weighs, we need to know how many feet are in a standard roll of wire. While the question does not specify the length of the roll, it's common for rolls of wire to contain anywhere from a few hundred to several hundred feet. If we take a typical length of 800 feet for a roll of wire (which is a common size for electrical wire), we can calculate the total weight of the roll:

Total weight = Length of the roll x Weight per foot = 800 feet x (1/8 pound per foot) = 100 pounds.

This calculation shows that if the wire roll contained 800 feet of wire
