Calculate Cube Edge Length from Face Area: 16 cm² Problem

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information.
• Step 2: Apply the formula for the area of a square to find the edge length.
• Step 3: Solve for the side length of the square face of the cube.

Now, let's work through each step:
Step 1: We know that each face of the cube has an area of 16 cm².
Step 2: The formula for the area of a square is $A = \text{side}^2$.
Step 3: We need to solve for the side length, so rearrange the formula: $\text{side} = \sqrt{A}$. Given $A = 16$, we find the side length: $\text{side} = \sqrt{16} = 4$ cm.

Therefore, the solution to the problem is $\text{the length of the cube's edges is } 4 \text{ cm}$.
