Answer
The cube that is 1 yard long, 1 yard wide, and 1 yard high is a unit cube.
Solution
A unit cube is defined as a cube with side lengths equal to 1 unit (whatever that unit may be). In this case, the only cube with a side length of exactly 1 (of its own unit) is the cube that is 1 yard long, 1 yard wide, and 1 yard high.
The other cubes have side lengths of 2 centimeters, 3 meters, and 9 inches, none of which are equal to 1 in their respective systems.
So, the correct answer is: the cube that is 1 yard long, 1 yard wide, and 1 yard high.

A unit cube is defined as a cube with each side measuring one unit in length. So, if we look closely at the options, none of them fit the precise definition of a unit cube, as they all exceed one unit in their dimensions. Think of a cube that's 1 cm x 1 cm x 1 cm – that’s a true unit cube! To visualize it further, imagine stacking up these larger cubes. Each of the options listed could contain multiple unit cubes within them! For example, the cube that is 3 meters long would fit a whopping 27 unit cubes inside. So, next time you're looking at cubes, think about how many unit cubes you can fill inside them!
