Inga [223]

Answer:

B. E(s) = s^3 - 29.

Step-by-step explanation:

The amount of empty space E(s) inside the cubic box is equal to the volume of the box minus the volume of the softball.

If the side length of the cubic box is s, and the volume of the softball is 29in^3, then the amount of empty space E(s) inside is

E(s) = s^3-29,

where s^3 is the volume of the cubic box.

Since it matches the equation we got above, choice B stands correct.
