What is the weight of 15 full 16' rails and 2 8' rails if each rail weighs 15lbs per foot?

3000lbs
3024lbs
3840lbs
4500lbs

The correct answer is: 3000lbs

To find the total weight of the rails, first, calculate the weight of the 16' rails and then the 8' rails individually. For the 16' rails: - Each rail weighs 15 lbs per foot. - Therefore, one 16' rail weighs: 16 feet x 15 lbs/foot = 240 lbs. - Since there are 15 of these rails: 15 rails x 240 lbs/rail = 3600 lbs. Next, calculate the weight of the 8' rails: - An 8' rail also weighs: 8 feet x 15 lbs/foot = 120 lbs. - For 2 of these rails: 2 rails x 120 lbs/rail = 240 lbs. Now, add the total weight of both sets of rails together: - Total weight = weight of 16' rails + weight of 8' rails = 3600 lbs + 240 lbs = 3840 lbs. Thus, the total weight of 15 full 16' rails and 2 8' rails is 3840 lbs, which corresponds to the choice that accurately reflects this total weight calculation.
