To make shelves for a bookcase, Nate needs 7 pieces of lumber, each 45 inches long. Nate has several 10-foot lengths of lumber in the width and thickness he needs. How many of these 10-foot boards will Nate use?

  • math -

    Each piece of 10-foot-long lumber has 120 inches (12*10).

    You need to figure how many times 45 goes into 120 to find the number of shelves Nate can get from each 10-foot long piece.

    If you post your answer and the number of 10-foot boards Nate will use, we'll be glad to check it.

    45 goes into 120 2 times.

  • math -

    Right. He can get 2 shelves out of each 10-foot board.

    Since he needs 7 shelves, how many pieces of lumber does he need?

  • math -

    about 4

  • math -

    You're right. :-) Nate needs 4 pieces of board to make his shelves.

  • math -

    Slight correction -- Nate needs four 10-foot long boards to make 7 shelves.

  • math -

    so the answer is 4. thanx!!! ur a big help!! went through it step by step.
