A rectangular block of clay measures 10 cm by 8 cm by 6 cm. Leonard used some of it to make three 4 cm cubes. He used the rest of the clay to make as many 5-cm cubes as possible. What was the maximum number of 5-cm cubes he could make?

    Leonard starts off with 480 cubic cm of clay. then takes away three 4cm cubes... these have a volume of 4x4x4=64 cubic cm each so take away 3*64 =192 total... 480 -192 = 288 cubic cm left.

    now Leonard is gonna make as many 5 cm cubes with what's left. each 5cm cube has volume 5x5x5=125 cubic cm.. how many of these do you think can be made with what's left?
