```
V = l × w × h
```
where:
* V is the volume in cubic feet
* l is the length in feet
* w is the width in feet
* h is the height in feet
In this case, the length is 60 feet, the width is 1 foot, and the height is 1 foot. So, the volume of the tank is:
```
V = 60 × 1 × 1 = 60 cubic feet
```
Therefore, the volume of the 60ft tank by 1ft deep is 60 cubic feet.
