To determine the total length of pipe needed, you need to add up the lengths of each individual piece together. The first step involves converting the measurements to a common format—it's often helpful to express everything in decimal form or keep them as fractions, but for ease of addition, we can convert to improper fractions or leave them in mixed number form.

1. **18 3/4 inches** can be converted to an improper fraction:

- \(18 \times 4 + 3 = 72 + 3 = 75/4\)

2. **8 1/8 inches** can also be converted:

- \(8 \times 8 + 1 = 64 + 1 = 65/8\)

3. **16 5/16 inches** as an improper fraction:

- \(16 \times 16 + 5 = 256 + 5 = 261/16\)

4. **24 1/2 inches** can be converted:

- \(24 \times 2 + 1 = 48 + 1 = 49/2\)

Next, you would need to convert these to a common denominator to sum them. The least common multiple of
