If a cube of Jello is cut into two pieces, what property of the pieces did not change?

The chemical structure.

When a cube of Jello is cut into two pieces, the property that does not change is the total volume of the Jello.

To understand why the volume remains the same after cutting, let's break it down:

1. A cube has six faces, all of which are congruent squares. Each face has equal dimensions, and all edges are of equal length. Let's say each side of the original Jello cube is "s".

2. The volume of the cube can be calculated by multiplying the length of any edge by itself twice (s × s × s), or by using the formula V = s^3.

3. Now, when the Jello cube is cut into two pieces, the overall volume doesn't change. One piece may be larger than the other, but the sum of their volumes remains the same.

4. Visualizing this, imagine cutting the Jello cube along any plane. Both resulting pieces will have the same height, width, and length as the original cube, just distributed differently. Therefore, their volumes will still be the same as the original volume.

In conclusion, when a cube of Jello is cut into two pieces, the one property that remains unchanged is the total volume of the pieces.
