Finish TradesCâu 263 / 700
A window unit has a glazed opening 4 feet wide by 5 feet tall in a room with 250 square feet of floor area. If the light requirement is 8 percent of floor area, does this single window meet it?
a.No; it provides only about 10 square feet of glazing
b.Yes; 20 square feet of glazing meets the 20-square-foot requirement
c.No; 8 percent of 250 is 40 square feet
d.Yes; only 5 square feet is required
Giải thích
The window glazing is 4 x 5 = 20 square feet, and 8 percent of 250 square feet is 20 square feet, so the single window exactly meets the natural light requirement. The window provides 20 (not 10) square feet, 8 percent of 250 is 20 (not 40), and the requirement is 20 (not 5) square feet.
