Introduction:
In this question, we are given a balanced scale with cubes on both sides. We need to determine the weight of one cube on the left side.

Given Information:
- The scale is balanced.
- Each cube on the left side weighs the same amount.

Approach:
To find the weight of one cube, we need to analyze the balanced scale and make some observations.

Observations:
1. The scale is balanced, which means the weight on the left side is equal to the weight on the right side.
2. Each cube on the left side weighs the same amount.

Analysis:
Since the scale is balanced and each cube on the left side weighs the same amount, we can conclude that the weight of one cube is equal to the weight of all the cubes on the right side.

Solution:
To determine the weight of one cube, we can follow these steps:

1. Count the number of cubes on the right side.
2. Calculate the total weight of all the cubes on the right side.
3. Divide the total weight by the number of cubes to find the weight of one cube.

Example:
Let's say there are 4 cubes on the right side, and the total weight of all the cubes on the right side is 20 units.

Weight of one cube = Total weight of all cubes / Number of cubes
Weight of one cube = 20 units / 4 cubes
Weight of one cube = 5 units

Conclusion:
Based on the given information and analysis, we can conclude that each cube weighs 5 units.
