Sam needs to cut a piece of sheet metal into 8 pieces. it takes him 5 minutes to make each cut. how many cuts will sam make? can you explain i got 8 cuts as my answer

If we assume Sam would achieve his aim of cutting the metal into 8 pieces.

Then he will make 8 cuts. It takes him 5 minutes to make each cut. This is how long it takes to make the cut. This only tells us that he will take a total of 8*5 = 40 minutes, to make all the cuts.
 
Sam will make 8 cuts as stated in the question.

3cm and 6 and 9 cm that a possibility of that question
