Core TradesQuestion 203 of 700
A roof plane rises at a 5:12 slope over a horizontal run of 15 feet. What is the vertical rise?
a.5.0 feet
b.5.75 feet
c.6.25 feet
d.7.5 feet
Explanation
Rise = run x (5/12) = 15 x 0.4167 = 6.25 feet. 5.0 ignores the run length, 5.75 uses an incorrect ratio, and 7.5 mistakenly applies a 6:12 slope instead of 5:12.
