Jena wants to paint the walls in her square shaped bedroom. each wall has an area of 130 sq ft. if one quart of paint covers 150 sq ft, how many quarts of paint will she need to buy to paint all four walls?
Would I leave it 4.6 or round up to five quarts?
Neither.
(130 * 4) / 150 = ?
Round up because nobody's going to sell you a part of a quart.
ok thanks
You're welcome.
To find out how many quarts of paint Jena will need, we need to calculate the total area of all four walls and then divide it by the coverage area of one quart of paint.
Given that each wall has an area of 130 sq ft, the total area of all four walls would be 4 * 130 sq ft = 520 sq ft.
Since one quart of paint covers 150 sq ft, we can now calculate the number of quarts Jena will need. We divide the total area of all four walls (520 sq ft) by the coverage area of one quart of paint (150 sq ft):
520 sq ft / 150 sq ft = 3.46
Now, to answer your question about whether to round up or not, it depends on how the paint is sold. If you can only purchase whole quarts, you would need to round up. In that case, Jena would need to buy 4 quarts of paint. However, if you can purchase partial quarts, you could buy 3.46 quarts (approximately 3 quarts and 1 pint) of paint.
Ultimately, the decision on whether to round up or down depends on the availability of partial quarts and your personal preference.
