Answer is 3813cm^3

First, find the volume of the sphere and cube.

Volume of sphere:
4/3 x pi x radius^3
4/3 x pi x 10^3
Sphere volume = 4188.790205

Volume of cube:
Length x width x height
20 x 20 x 20
Cube volume = 8000

Afterwards, subtract the volume of the cube by the volume of the sphere.

8000 - 4188.790205 = 3811.209....

The volume of the cube not filled by the sphere is 3811.209. Option A is the correct.

What is volume?

The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic m.

The volume of sphere is found as;;

[tex]\rm V_{sphere}= \frac{4}{3} \pi r^3 \\\\ V_{sphere}= \frac{4}{3} \times 3.14 (10)^3 \\\\ V_{sphere}= 4188.79 \ cm^3[/tex]

The volume of cube is found as;

Volume of cube = Length x width x height

Volume of cube =20 x 20 x 20

Volume of cube = 8000

The volume of the cube not filled by the sphere is found by subtract the volume of the cube by the volume of the sphere.

V=8000 - 4188.790205

V = 3811.209

The volume of the cube not filled by the sphere is 3811.209.

Hence, option A is the correct.
