Abox contains 9 identical glass spheres that are used to make snow globes. the spheres are tightly packed. they are held in a 12ft by 12ft box.
what is the total volume, in cubic inches, of all 9 spheres? round your answer to the nearest tenth of a cubic inch.
volume of a sphere= 4/3 πr^2

Because the balls or spheres are tightly packed in a cube, their radius is approximately equal to 2 ft. The volume of a sphere is calculated through the equation,
                                           V = 4/3πr³
Substituting the known radius,
                                           V = 4/3π(2 ft)³
                                           V = 33.51 ft³
The 9 spheres will have a total volume of 301/59 ft³ which is also equal to 521152.52 in³.
