It is given in the question that :

A crate of tennis balls measures 25 inches by 25 inches by 15 inches.

First we have to find the volume of the crate which is


Volume = 25*25*15 = 9375 inches^3

And the given radius of tennis ball is 1.35 inches .

A tennis ball is in the shape of sphere. And volume of sphere is


Volume = (4)/(3) \pi r^3

Substituting the value of r, we will get


Volume = (4)/(3) * \pi * 1.35^3 = 10.31 inches^3

TO find the number of balls , we have to divide the volume of crate by volume of ball.

That is ,


= (9375)/(10.31) = Approx 910 balls
