In elementary school we had a competition like this where we had to make something that would protect an egg being thrown of the gym roof( 30ft).
I took a bleach jug and cut a door/flap( top/bottom/one side) that I could open reach through to place the egg. The plastic was stff enough to spring back to hold the door closed. I lined the interior with bubble wrap. I placed 4-5 full layers on the bottom, then I placed layers that had a hole in the center to hold the egg snugly in place. I left enough room so I could still grab/remove the egg. I then made a hole in the cap were I tied stings that ran up to a parachute I made out of plastic( painters drop cloth). The parachute needs to be cut in a multi point star shape so it opens properly. You can test it without the egg to adjust the string length.
The end result was so well thought out, it could have be deployed from a plane and not break the egg.
20 feet!20 feet!20 feet!20 feet!
20 x 20 = 400 square feet.
If the given dimensions are in feet then there are: 20*20*20 = 8,000 cubic feet
6' x 20' = 120 square feet.
20 yards = 60 feet
4.8 inches
Wrap it around 6 times with bubble wrap. The egg drop experiment is a standard science engineering project. The idea is to build a container for the egg out of simple materials and drop the egg from a determined height. This container is meant to protect the egg from breaking. the easy way :: if you hold the egg slightly above 6' it will fall 6' without breaking ..its the last little bit that does all the damage
20 feet!20 feet!20 feet!20 feet!
20 x 20 = 400 square feet.
Do you mean a real square with the side length of 20 feet? Then 20 feet times 20 feet is 400 square feet.
If the given dimensions are in feet then there are: 20*20*20 = 8,000 cubic feet
20 feet x 24 feet = 480 feet.
20
The answer is 400 sq feet.
Exactly 20 feet.
20 feet * 30 feet = 600 feet squared ==============
20 cm = 0.656 feet.
