Three pieces of wood are needed for a project.
They are to be cut from a 90-cm-long piece of
wood. The longest piece is to be 3 times as long as
the middle-sized piece and the shortest piece is to
be 10 cm shorter than the middle-sized piece. Can
this be done with two cuts? If so, tell how.

  • math - ,

    The pieces are 10 cm, 20 cm, and 60 cm. I don't think this can be done with two cuts. I think that you woudl need three.

  • math - ,

    After cutting off a 60 cm piece, and 20 cm off the remaining 40 cm, you will be left with 10 cm. That is two cuts. You could also change the order.
