Question

Construction One linear foot of 12-in. I-beam weighs 25.4 lb. What is the length of a beam that weighs 444.5 lb?

Answer 1

17.6 feet.

Explanation:

The length of the I-beam can be calculated as follows:

Weight = Length * Weight per Foot

Rearranging this equation:

Length = Weight / Weight per Foot

Substituting the given values:

Length = 444.5 lb / 25.4 lb/ft = 17.6 ft

So, the length of the I-beam is 17.6 feet.
