A worker in a factory stacks metal sheets on top of each other. The first sheet is 7.448 centimeters thick. Next comes a sheet that is 7.927 centimeters thick, and then a third sheet that is 2.9 centimeters thick. When the worker is done stacking them, how thick will the stack of metal sheets be?

1 answer

To find the total thickness of the stack of metal sheets, we add the thicknesses of each sheet: 7.448 cm + 7.927 cm + 2.9 cm = <<7.448+7.927+2.9=18.275>>18.275 cm. Answer: \boxed{18.275}.
