Answer:
180
Explanation:
At the beggining, it says they are stacked in 5 layers which means the number of cubes is divisible by 5.
If the number of cubes equals x:
The least amount of sugar cubes the Jones family could have used is
which equals 122. The most they could've used is
which equals 183.
Based on the information from the Jones family, x is between 122 and 183.
Based on the information from the Connor family, x is between 176 and 264.
Based on the information from both, x is between 176 and 183. The only number that is divisible by 5 between those numbers is 180 cubes.
