To determine the size range of refrigerators that Shriya should consider, we need to account for the space available (26 ft³) and ensure that the new refrigerator can fit while allowing for some clearance.
A good rule of thumb is to leave some space for proper airflow and to ensure the refrigerator is easy to install. Typically, leaving about 2 to 3 inches of space around the unit is recommended.
If we consider an allowance for clearance, let's say we allow 2 ft³ of space for airflow and installation.
So, if the available space is 26 ft³, we subtract the clearance:
26 ft³ (available space) - 2 ft³ (clearance) = 24 ft³.
Therefore, the size range of refrigerators she should consider would be:
Between 20 ft³ (current size) and 24 ft³ (adjusted for clearance).
So, Shriya should consider refrigerators that are between 20 ft³ and 24 ft³.
