A cube is a three-dimensional geometric figure, where all three dimensions are equal in length. These three dimensions are length, width, and height.
Here’s a step-by-step explanation:
1. Definition of a Cube:
- A cube is a solid figure with six equal square faces. All the edges of these faces have the same length.
2. Dimensions of a Cube:
- Since a cube is a three-dimensional object, it must have three measurements to define its size fully. These measurements are traditionally called length, width, and height.
- In a cube, all three dimensions (length, width, and height) are of the same magnitude.
3. Analyzing the Options:
- Option A: Length and width only: This option is incomplete. Length and width alone define a two-dimensional rectangle or square, not a three-dimensional cube.
- Option B: Length, width, and height: This option is complete and accurate. It describes a three-dimensional object, where all three dimensions are specified.
- Option C: Length only: This option is insufficient. Length alone defines a one-dimensional line.
- Option D: None of these: This option is incorrect because there is a correct answer provided in the choices.
So, the correct answer is B: Length, width, and height.
