Planning & Estimating第 78 / 100 题
A sod order covers 2,700 square feet. Sod is sold in pieces covering 10 square feet each. Roughly how many pieces are needed, ignoring waste?
a.27 pieces
b.135 pieces
c.270 pieces
d.2,700 pieces
解析
Divide the total area by the coverage per piece: 2,700 divided by 10 equals 270 pieces. Installers usually add about 5 percent extra for cuts and irregular edges. Ordering by coverage prevents running short mid-installation.
