Final answer:
The dimensions of the base of Box 1 are x, 3x, x + 3, and x - 3. The dimensions of the larger square are twice the dimensions of the first square, so the side length of the larger square is 2x.
Step-by-step explanation:
The base of Box 1 has four different dimensions:
- Width: x
- Length: 3x
- Width: x
- Length: x + 3
- Width: x
- Length: x - 3
- Width: x
- Length: 3x
To find the dimensions of the larger square, you need to use the information given. The dimensions of the larger square are twice the dimensions of the first square. So, the side length of the larger square is 2x.
