Question

A tennis ball has a diameter of 2.7 in. How many tennis balls will fit inside of a storage

Answer 1

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.

$x=\dfrac{\text{Volume of box}}{\text{Volume of 1 tennis ball}}\\\\x=\dfrac{4\times 2.5\times 2}{\dfrac{4}{3}\pi \times (\dfrac{2.7}{3})^3}\\\\x=6.54$

Approximately

x = 7

Hence, there are 7 balls.
