Hi there! I’m happy to help you!
1. The length of one side of the park is 60 meters. 3,600 squares is 60.
2. The length of the edge of the container is 20. 8,000 cubed is 20.
3. The area of the base will definitely be greater than one square foot. 1,000 cubed is 10. 10 * 10 is 100. 100 square inches is equivalent to 8 1/3 square feet.
