Sherry‘s current refrigerator has a volume of 20 feet with a small tree on top of the space she has for the refrigerator is 26 feet with the small three on top Sherry decides to buy a new refrigerator. What sizes of refrigerators should she consider?

To determine the size of the new refrigerator Sherry should consider, we need to subtract the size of the small tree on top from the available space for the refrigerator.

Sherry has a total space of 26 feet, and the small tree takes up some space on top of the refrigerator. Let's assume the small tree takes up 4 feet of space.

So, the available space for the new refrigerator would be:

26 feet - 4 feet = 22 feet

Therefore, Sherry should consider refrigerators with a volume of around 22 feet or less to fit in the available space with the small tree on top.
