suppose a cube of jell-o is cut into two pieces. What property stays the same when comparing the original piece with one of the new pieces?

a. density
b. mass
c. volume
d. surface area

What do you think? Can you eliminate any choices? Come on now; think about it.

When a cube of Jell-O is cut into two pieces, the property that stays the same when comparing the original piece with one of the new pieces is the density.

To understand why density remains the same, let's define density. Density is defined as the mass of an object divided by its volume. Mathematically, density = mass / volume.

When a cube of Jell-O is cut into two pieces, the mass of the Jell-O is distributed between the two pieces. However, since both pieces come from the same cube of Jell-O, they have the same total mass.

Similarly, the volume of the Jell-O cube is also distributed between the two pieces. Again, because both pieces come from the same cube, they have the same total volume.

Since the mass and volume of both the original piece and one of the new pieces remain the same, when we calculate the ratio of mass to volume (density) for both pieces, they will yield the same value. Hence, the density of the original piece and one of the new pieces is the same.

Therefore, the correct answer is a. density.
