Final answer:
To calculate the number of tennis balls needed to fill a bedroom, you need to find the volume of the bedroom and divide it by the volume of one tennis ball.
Step-by-step explanation:
To calculate the number of tennis balls needed to fill a bedroom, we first need to find the volume of the bedroom by multiplying its length, width, and height. The volume of the bedroom is 11 ft x 12 ft x 8 ft = 1056 cubic feet.
Next, we divide the volume of the bedroom by the volume of one tennis ball. The volume of one tennis ball can be found by calculating the volume of a sphere using its diameter. A tennis ball with a diameter of 2.5 inches has a volume of (4/3) x π x (1.25^3) cubic inches.
Since 1 cubic foot is equal to 1728 cubic inches, we convert the volume of one tennis ball to cubic feet. Finally, we divide the volume of the bedroom by the volume of one tennis ball to find the number of tennis balls needed.
