A quart of water weighs about 2.09 pounds. What is the approximate weight of 15.5 quarts of water? 20
The Correct Answer and Explanation is:
To find the approximate weight of 15.5 quarts of water, we can multiply the weight of one quart by the number of quarts.
Given:
- 1 quart of water weighs about 2.09 pounds.
- You need to find the weight of 15.5 quarts of water.
Step 1: Multiply the weight of one quart by the number of quarts.
Weight of 15.5 quarts=15.5×2.09\text{Weight of 15.5 quarts} = 15.5 \times 2.09Weight of 15.5 quarts=15.5×2.09Weight of 15.5 quarts=32.295 pounds\text{Weight of 15.5 quarts} = 32.295 \text{ pounds}Weight of 15.5 quarts=32.295 pounds
So, the approximate weight of 15.5 quarts of water is 32.3 pounds.
Explanation:
The weight of water is a common unit of measurement, and this approximation is based on the fact that one quart of water weighs roughly 2.09 pounds at standard conditions. This relationship is crucial in various practical applications, such as shipping, cooking, and science experiments.
Since the weight of water can be affected by temperature and pressure (for example, warmer water can be slightly less dense), the number we used (2.09 pounds per quart) is based on standard conditions. The calculation here assumes that the water is at these standard conditions and that you’re looking for an approximation.
Thus, by multiplying the number of quarts (15.5) by the weight of one quart (2.09 pounds), we determine the total weight of the water in pounds.
