48 centimetre cubes fit exactly into the bottom of this box with length 8 cm, width 6 cm and height 5 cm. how many cm cubes are needed t fill it?
me.

So find volume of 1 cube
and find volume of box
then divide volume of box by volume of 1 cube

volume of box=legnth times width times height=8 times 6 times 5=240
then it is not clear how much volume the cube is but I think it is 48 so
240/48=5
5 cubes will fit (theoretically, if they are melted in)
