Explanation:
It is known that the volume of a rectangular prism is calculated as the product of its length, width, and height. In this case, the length and width of the tank are not specified, so they cannot be used in the calculation. However, the height of the tank is given as 1 inch.
To find the volume of 1 inch of the tank, the total volume of the tank (275 gallons) must be divided by the height (1 inch). This calculation can be performed as follows:
```
Volume of 1 inch of the tank = Total volume of the tank / Height
= 275 gallons / 1 inch
= 275 gallons/inch
```
Therefore, the volume of 1 inch of the tank is 275 gallons/inch.
