In a 3D (three-dimensional) shape, the three dimensions are:
- Length – This is how long an object is, measured from one end to the other along a straight line.
- Width – This is the measurement of the object from one side to the other, typically at a right angle to the length.
- Height – This is how tall the object is, measured from the base to the top.
These three dimensions give us the full size and shape of an object in three-dimensional space, like a box, sphere, or cube.
