A factory makes sheets of metal that are 3 1/2
inches thick. If a worker at the factory makes a stack of 3 of the sheets, how many inches thick will the stack be?
The thickness of one sheet is 3 1/2 inches. To find the thickness of the stack of 3 sheets, we simply multiply the thickness of one sheet by 3.
3 1/2 inches x 3 = 10 1/2 inches
Therefore, the stack of 3 sheets will be 10 1/2 inches thick.
