To find the area of the cardboard needed to make a cube using the given dimensions, we first need to understand what the dimensions represent.
The numbers provided seem to represent the dimensions of a cube where:
- The edge length of the cube is \(3\) inches (as we see there are several instances of \(3\)).
- The numbers \(6\) could refer to the areas of the six faces of a cube or simply help in visualizing the layout of the "box net."
Step-by-step breakdown:
-
Understanding the Cube Dimensions:
- A cube has six faces and each face is a square.
- Since the edge of the cube is \(3\) inches, each square face has an area of: \[ \text{Area of one face} = \text{side}^2 = 3^2 = 9 \text{ square inches} \]
-
Calculating Total Area:
- Since a cube has 6 identical square faces, the total surface area \(A\) of the cube is given by: \[ A = 6 \times \text{Area of one face} = 6 \times 9 = 54 \text{ square inches} \]
-
Conclusion:
- The total area of cardboard needed to make the cube is: \[ \boxed{54} \text{ square inches} \]
