Step-by-step explanation:
Given that,
The diameter of a tennis ball, d = 2.7 inches
We need to find the number of tennis balls will fit inside of a storage unit that is 4 feet wide, 2.5 feet long, and 2 feet high.
Let there are x number of tennis balls.
[tex]x=\dfrac{\text{Volume of box}}{\text{Volume of 1 tennis ball}}\\\\x=\dfrac{4\times 2.5\times 2}{\dfrac{4}{3}\pi \times (\dfrac{2.7}{3})^3}\\\\x=6.54[/tex]
Approximately
x = 7
Hence, there are 7 balls.
