A shipment of boxes has an average of 90 tiles per box. If three boxes are added, each of which has 87 tiles, and the shippers are preparing the final box for the shipment, how many tiles must be in this box in order to maintain an average of 90 tiles per box?

73.6 inches cubed.

Step-by-step explanation:

The softball is a sphere. Its diameter is 5.2 inches, which means its radius is 5.2 / 2 = 2.6 inches.

The volume of a sphere is (4/3)pi * r^3.

(4/3) * pi * (2.6)^3

= (4/3) * 3.14 * 17.576

= (4/3) * 55.18864

= 73.58485333.

That means that the softball's volume is about 73.6 inches cubed.

Hope this helps!
