Question 10
8 rectangular containers, each measuring 12cm by 10cm by 7cm are filled completely with water. If the water from the 8 containers is poured into a big rectangular tank measuring 40cm by 20cm by 15cm, find the fraction of the tank that will be empty.
**Editorial note for this self-study exercise:** Use internal container dimensions and assume no water is lost. Enter the empty fraction of the whole tank, as an exact fraction or exact decimal using a decimal point.
