estimate the number of table tennis balls that would fit (without being crished) into a room that is 4 m long, 4 m wide, and 3 m
Mumz [18]
The diameter of a ball is 3.8 cm.

Because 400/3.8 = 105.26,
each dimension of 400 m can accommodate 105 balls.
Similarly, because 300/3.8 = 78.95,
each dimension of 300 m can accommodate 78 balls.

The total number of balls is 105*105*78 = 859,950

Answer: 859,950 balls
