Lizzy: An iron bar measures 12 cm by 8 cm by 6 cm. A factory wants to melt ten iron bars and mold them into iron balls. Each iron ball has a volume of 8 cubic cm. How many iron balls have been molded?.
Me: Hmmm, let me think. I think this is the detailed solution:

The volume of 1 iron bar is 12 cm x 8 cm x 6 cm = 576 cubic cm. The volume of 10 iron bars is 10 x 576 cubic cm = 5760 cubic cm. Therefore, there are 5760 / 8 = 720 iron balls that have been molded. Final answer: 720.
