Mr. Cline needs 36 ice cubes for the science experiment. Eack ice tray makes 12 ice cubes. If he makes 4 ice trays, does he have enough ice cubes? Can you use an estimate to solve? Explain.

  • math -

    what is 12 x 4 ?

    as an estimate what is 10 x 4 ?
    (suppose each tray has only 10 cubes)
