Sam needs to cut a piece of sheet metal into 8 pieces. it takes him 5min to make a cut how many cuts will sam and how long will it take sam to turn the sheet metal into 8 piece?

Now this is assuming the pieces of sheet metal are strips that are cut away from the original object.
8 cuts's
40 min

It will take Sam 35 minutes to cut the sheet metal into 8 pieces. To cut an object into 8 pieces, you make 7 cuts. You can see this if you draw a rectangle on a piece of paper and divide it into 8 pieces. Since it takes Sam five minutes to make a cut, you multiply 7 by 5. 7x5=35, so it will take Sam 35 minutes to cut the sheet metal into 8 pieces. Hope this helps!
