The plan scale is 1/4 inch = 1 foot. A water line measures 5 inches on the drawing. What is the actual pipe length?
a.5 feet
b.15 feet
c.20 feet
d.25 feet
Giải thích
At 1/4 inch = 1 foot, each inch on paper equals 4 feet, so 5 inches × 4 feet = 20 feet. Converting scaled measurements to real lengths is the basis of accurate takeoffs. Double-check the title-block scale before measuring, since sheets in a set can use different scales.
