If a large ball left a gap near the corner for a smaller ball, the smaller ball will also leave a gap near the corner for a still smaller ball ! :)

Now you don't have to think outside the box! The equations get a little more complex ! A little more stress ! :)

but ur question was whether a 7cm dia ball can pass through the gap. the answer is yes. What is the problem if there's still a gap. :huh:

Now, you have to think outside the box ! :) Extend the line connecting the corner to the center of the large 40 cm diameter ball to the surface of the ball. The length of that line is 48.28 cm. But the diameter of the ball is 40 cm. If similar length is 8.28 cm what will be diameter of the largest ball? In other words you have to find out the diameter of the largest ball that can pass through that gap. Only then you can make a conclusion. Try 8.25 cm diameter ball. You will have to make a dent in the wall and the floor! :) 8.25 < 8.28 ! :)

oops, technical fault.
7cm dia ball cant pass through the gap.
A Ball with dia less than 6.86cm can pass through the gap.

GP: :)

Let us move to triangles:

Two right angled triangles have a common hypotenuse (joined at the hypotenuse of same length). The other two sides of one triangle are 18 and 13 units. The other two sides of the second triangle are 20 and 7 units.
Obviously the units are not decimal (base ten numbers). What is the length of the hypotenuse and what is the base used?

All of you seem to be in IT sector. This should be stress relief for you! :)

i yaam in construction sector, but work yellAm computer la thaan. :)

தசம எண்கள் கிடையாதா? :confused2:
பித்தாகரஸ் தேற்றம் கைகொடுக்கவில்லையே :huh:

Pythogorean theorem will help to find the base(not decimal)! :) First you have to solve for the unknown base ! :)

If two triangles have common hypotenuse, it should be a rectangle, right (for any base)? :?

No! Draw a circle with the hypotenuse as the diameter. Pick any point on the circle. The diameter will subtend a right angle ! :) It is known as Thales' theorem!
