what is the amount of space, in cubic units, occupied by a three-dimensional object?

More data needed (length, height, width).

To determine the amount of space, in cubic units, occupied by a three-dimensional object, you need to calculate its volume. The volume of a three-dimensional object is the measure of how much space it occupies.

The formula to calculate the volume of various geometric shapes is as follows:

- Cube: Volume = Length x Width x Height
- Rectangular Prism: Volume = Length x Width x Height
- Cylinder: Volume = π x Radius^2 x Height
- Sphere: Volume = (4/3) x π x Radius^3
- Cone: Volume = (1/3) x π x Radius^2 x Height
- Pyramid: Volume = (1/3) x Base Area x Height

For example, if you have a cube with sides measuring 5 units, you can calculate the volume by substituting the values into the cube formula:

Volume = Length x Width x Height
= 5 units x 5 units x 5 units
= 125 cubic units

Therefore, the amount of space occupied by the cube is 125 cubic units.

Remember to use the appropriate formula for the shape of the three-dimensional object you are working with to calculate its volume.
