What is the weight of a 12" diameter pipe that is 48' long and weighs 35 lbs per linear foot?

To determine the total weight of a 12" diameter pipe that is 48' long and weighs 35 lbs per linear foot, you start by calculating the weight based on the length of the pipe.

First, find out the total length of the pipe in feet, which is given as 48'. Next, use the weight per linear foot, which is provided as 35 lbs. The calculation for the total weight can be performed by multiplying the length of the pipe by the weight per linear foot:

Total Weight = Length of Pipe × Weight per Linear Foot Total Weight = 48' × 35 lbs/ft

Carrying out the multiplication:

Total Weight = 1680 lbs

This calculation indicates that the total weight of the pipe is indeed 1680 lbs, which corresponds to the correct choice in the provided options.
