It depend on your tent building skills. If you're experienced, which I doubt you are, it could take about 15 minutes but if you aren't, it could take over an hour.
No! If you install a 10ft trampoline safety enclosure onto an 8ft trampoline, it may look like it fits, but it will not provide effective protection. Trampoline safety enclosures are fundamental, but it is key to ensure that the right sized enclosure is fitted onto the correct sized trampoline.
To calculate the material needed for the triangular tent, we first determine the surface area of the tent. The tent consists of a triangular front and back and a rectangular base. The area of each triangular side is 0.5 × base × height = 0.5 × 24 ft × 5 ft = 60 sq ft, and with two sides, that totals 120 sq ft. The area of the rectangular base is 20 ft × 24 ft = 480 sq ft. Therefore, the total material needed for the tent is approximately 600 sq ft.
15 ft * 15 ft = 15*15 sq ft = 225 sq ft
