Briefly

The Eiffel Tower

The Eiffel Tower

The Eiffel tower is 320 meters high and weighs 7,000 tons. If we built a perfectly scale model, with the same material and that was half its height, How much would it weigh?

Solution

Would weigh 875 tons. Not only the height of the tower is reduced, but also its width and depth, so that its weight decreases to an eighth of the original weight.
