How much conduit is needed if the rise is 15", the leg length is 10", and the gain is 8.6"?

To determine how much conduit is needed based on the given rise, leg length, and gain, we can use the principles of geometry to compute the total length of conduit required.

First, we can visualize the conduit running through a triangle formed by the rise, leg length, and gain. The rise represents the vertical distance, the leg length is the horizontal distance, and the gain can be thought of as the additional distance the conduit covers along the incline.

The total conduit length can be calculated using the formula: Total Conduit Length = Rise + Leg Length + Gain.

When we plug in the provided values:

• Rise = 15 inches

• Leg Length = 10 inches

• Gain = 8.6 inches

Calculating it gives us:

Total Conduit Length = 15 + 10 + 8.6 = 33.6 inches.

This total corresponds to the option listed as 33.6 inches, which is why it is the correct answer. The other choices do not accurately reflect the sum of the rise, leg length, and gain, making them unsuitable for this particular calculation.
