Question

water leaves a spigot at a rate of 462 cubic inches per minute. how many cubic feet of water is this per hour? (round your answer to the nearest whole number.)

□ cubic feet

Explanation:

Step1: Convert minutes to hours

There are 60 minutes in an hour, so the total cubic inches per hour is \( 462 \times 60 \) cubic inches.
\( 462\times60 = 27720 \) cubic inches per hour.

Step2: Convert cubic inches to cubic feet

Since 1 foot = 12 inches, 1 cubic foot = \( 12^3=1728 \) cubic inches. So we divide the total cubic inches by 1728 to get cubic feet: \( \frac{27720}{1728} \).

Step3: Calculate and round

\( \frac{27720}{1728}\approx16.0417 \), rounding to the nearest whole number gives 16.

Answer:

16
