Planning & Estimating第 85 / 100 题
To coat 2,000 sq ft with a product covering 250 sq ft per gallon (rough surface), about how many gallons are needed per coat?
a.4 gallons
b.5 gallons
c.8 gallons
d.10 gallons
解析
Gallons equal area divided by spread rate: 2,000 / 250 = 8 gallons per coat. The lower spread rate reflects a rough, absorbent surface that consumes more paint. Multiply by the number of coats and round up when purchasing.
