A quart is approximately sixty cubic inches. A cubic feet of water weighs approximately sixty pounds. Therefore, a quart of water weighs approximately
A. 2 lbs
B. 3 lbs
C. 4 lbs
D. 5 lbs
well, a cubic foot is 12^3 = 1728 cubic inches. So,
1qt * 60in^3/qt * 1ft^3/1728in^3 * 60lb/ft^3 = 3600/1728 = 2.08 lb
To find the weight of a quart of water, we need to convert the volume in cubic inches to cubic feet.
Since there are 12 inches in a foot, we can find the number of cubic feet by dividing 60 cubic inches by (12 inches/foot) * (12 inches/foot) = 144 cubic inches/foot^2.
Therefore, a quart of water is equivalent to 60 cubic inches / 144 cubic inches/foot^2 ≈ 0.4167 cubic feet.
Now, we can calculate the weight of a cubic foot of water by multiplying the volume by the weight per cubic foot, which is approximately 60 pounds.
Weight = (0.4167 cubic feet) * (60 pounds/cubic foot) ≈ 25 pounds.
Therefore, a quart of water weighs approximately 25 pounds.
The correct answer is not provided in the options given.
To find the weight of a quart of water, we need to convert cubic inches to cubic feet.
Given that a quart is approximately 60 cubic inches, we can calculate the conversion as follows:
1 cubic foot = 12 inches × 12 inches × 12 inches = 1,728 cubic inches
Now, let's find the weight of 1 cubic foot of water, which is approximately 60 pounds.
Next, divide the weight of 1 cubic foot of water by the number of cubic inches in 1 cubic foot:
Weight of 1 cubic foot of water = 60 pounds
Number of cubic inches in 1 cubic foot = 1,728 cubic inches
Weight of 1 cubic inch of water = 60 pounds ÷ 1,728 cubic inches = 0.0347 pounds (approximately)
Finally, to find the weight of a quart of water, multiply the weight of 1 cubic inch of water by 60 cubic inches:
Weight of a quart of water = 0.0347 pounds/cubic inch × 60 cubic inches = 2.08 pounds (approximately)
Therefore, a quart of water weighs approximately 2 pounds (Option A).
