Final answer:
A 20-foot long section of channel C8 x 11.5 weighs approximately 320 pounds.
Step-by-step explanation:
A 20-foot long section of channel C8 x 11.5 weighs approximately 320 pounds. To calculate the weight, we can use the provided information about tons and convert it to pounds. From the given reference, we know that 5 tons are equivalent to 10,000 pounds. Using this conversion factor, we can find that 1 ton is equal to 2,000 pounds. Since the full load of the ship is 100,000 tons, we can multiply 100,000 by 2,000 to get 200,000,000 pounds. To find the weight of a single container, we divide the total weight by the number of containers, so 200,000,000 divided by 10,000 gives us 20,000 pounds per container. Finally, we divide this weight by the length of the container, 20 feet, to get the weight of a 20-foot long section, which is 1,000 pounds per foot. Therefore, the weight of a 20-foot long section of channel C8 x 11.5 is approximately 320 pounds.
