You plan to stain a wooden deck that measures 16 ft by 18 ft. A quart of stain will cover 70 ft². How many quarts of stain should you buy?

Question

Quizplus · Accepted Answer

To find the total area of the deck, we compute the product of its length and width:

16 ft x 18 ft = 288 ft^2

We need to cover 288 ft^2 with stain, and each quart covers 70 ft^2, so we divide:

288 ft^2 ÷ 70 ft^2/qt ≈ 4.11 qt

We need to round up to the nearest whole number of quarts, since we can't buy a fraction of a quart. Thus, we need to buy 5 quarts of stain to cover the entire deck.
