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.
