$$E _ { L I N E } = \sqrt { E _R ^ { 2 } + E_ X ^ { 2 } }$$

Short Answer

$$E _ { L I N E } = \sqrt { E _R ^ { 2 } + E_ X ^ { 2 } }$$ To run a 3-wire cable, a hole is drilled through a plate, the subflooring, and the finished flooring. The plate is 1.6 centimeters, and the subfloor is 3.4 centimeters and the finished flooring is 8 millimeters. Find the depth of the hole in centimeters. Carry the answer to one decimal place.
