A quart of stain covers 100 square feet. How many quarts should you buy to stain the ramp? (Assume you do not have to stain the bottom of the ramp.)


Answer:
270.6 or 2.7 Quart or about 3 quart of stain.
Step-by-step explanation:
From the given example, we recall the following,
A quart of stain covers (100) square feet
Let The 30 in. be converted to 2.5 feet
Then,
The sides:
(30 x 2.5) ÷ 2 = 37.5
37.5 + 37.5 = 75
For the Back:
2.5 x 6 = 15
Top:
30.1 x 6 = 180.6
180.6 + 75 + 15 = 270.6 or 2.7
Therefore, about 3 quarts of stain is needed
