Step-by-step explanation:
The number of tennis ball that will fill the room is <u>1,371 tennis balls.</u>
<em><u>Given</u></em>:
Diameter of ball (d) : 2 inch
Radius (r) = half of diameter = 1 inch
Dimension of room = 20ft by 16ft by 18ft
Number of balls that will fill the room = Volume of each ball/volume of the room
Volume of the ball = volume of a sphere = 
Where,
r = 1
let 
<em>Substitute</em>:

Volume of the room = 

Therefore:
number of tennis balls that will fill the room = 
Therefore, the number of tennis ball that will fil the room will be <u>approximately 1,371.</u>
