The amount of square feet that 5 cubic feet of pea gravel will cover depends on the depth at which it is spread. To calculate this, we will use the formula:

```

Area = Volume / Depth

```

Given:

- Volume = 5 cubic feet

Let's assume two different depths:

Depth 1: 1 inch (0.0833 feet)

```

Area = 5 cubic feet / 0.0833 feet

= 60 square feet

```

Therefore, 5 cubic feet of pea gravel will cover 60 square feet when spread to a depth of 1 inch.

Depth 2: 2 inches (0.1667 feet)

```

Area = 5 cubic feet / 0.1667 feet

= 30 square feet

```

Therefore, 5 cubic feet of pea gravel will cover 30 square feet when spread to a depth of 2 inches.

It's important to note that these calculations assume the pea gravel is spread evenly and without any compaction. In reality, some compaction may occur, which would slightly reduce the actual coverage area.
