We are supposing that the 3392.92 cubic inches of liquid will fit perfectly into the 30 glass spheres.
The volume of a sphere is:
(4/3) * pi * r^3
30 of these would be:
30 * [(4/3) * pi * r^3] = 3392.92
Divide by 30 and 4/3:
pi * r^3 = 84.823
Divide by pi and cube root each side:
r is about 3 inches, meaning the diameter is about 6 inches.
The answer is (C).
