Question

Using 1 3-foot by 8 foot piece of sheet metal, an installer makes four 6 inch circular ducts. Each duct is 3 feet long. How many ducts can be made from 26 sheets of metal

Answer 1

Answer: 104

Explanation:

Given: Using one 3-foot by 8 foot piece of sheet metal, an installer makes four 6 inch circular ducts.

Thus, the number of ducts made by 1 sheet= 4

By using direct proportion, the number of ducts made by 26 sheets is 26 times the number of ducts made by 1 sheet.

The number of ducts made by 26 sheets =
`4*26=104`

Hence, the number of ducts made by 26 sheets = 104
