The food container Elena bought is a cube with each side measuring 10 cm. The volume $V$ of a cube is calculated using the formula:

$V = s^3$

where $s$ is the length of a side. Plugging in the given measurement:

$V = 10^3 = 10 \times 10 \times 10 = 1000 \text{ cubic centimeters (cm}^3\text{)}$

So, the volume of the food container is 1000 cubic centimeters (cm³).

Would you like further details or have any questions?

Here are some related questions:

1. How would the volume change if each side were doubled?
2. What is the surface area of the food container?
3. If the container was half-filled with water, how much water would it contain?
4. How would you calculate the volume if it were a rectangular prism instead of a cube?
5. How do you convert the volume from cubic centimeters to liters?

Tip: The volume of a cube increases dramatically as the side length increases, following the cubic relationship $V = s^3$.
