A sphere with diameter 1 unit is enclosed in a cube of side 1 unit each. Find the unoccupied volume remaining inside the cube.

A sphere with diameter 1 unit is enclosed in a cube of side 1 unit each. Find the unoccupied volume remaining inside the cube.

This looks like a geometry or physics question. The GRE covers many subjects. If you want a tutor in this subject matter to see your question, please follow directions. You should be able to do that if you are taking the GRE.

To find the unoccupied volume remaining inside the cube, we need to subtract the volume of the sphere from the total volume of the cube.

The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere. In this case, since the diameter is 1 unit, the radius would be 1/2 units.

The volume of the sphere is therefore V = (4/3)π(1/2)³ = (4/3)π(1/8) = π/6.

The volume of a cube is given by the formula V = side³. In this case, since the side is 1 unit, the volume of the cube is V = 1³ = 1.

Now, to find the unoccupied volume remaining inside the cube, we subtract the volume of the sphere from the volume of the cube.

Unoccupied volume = Volume of cube - Volume of sphere = 1 - π/6.

Thus, the unoccupied volume remaining inside the cube is 1 - π/6 units^3.
