Answer:

  120 cubes

Step-by-step explanation:

This kind of problem can be easier to work if you rewrite the prism dimensions in terms of cube dimensions. For 2 cm cubes, the prism dimensions are ...

  • 12 cm = 6 cube lengths
  • 20 cm = 10 cube lengths
  • 4 cm = 2 cube lengths

As always, the volume of the rectangular prism is the product of its dimensions:

  V = (6)(10)(2) = 120 cubes

120 2-cm cubes will fit int the rectangular prism.
