–:  The ruler that is of 1 feet length have 12 inches and is equivalent to 30.48 cm. A rectangular box measured 40 cm by 40cm have a height of 50 cm and inside this rectangular box, a ball that fits into the rectangular box have a radius of 19 cm. The 3 dimension rectangular box and ball have a mass of 3.5 kg. The ball and the rectangular box are turned upside down. If the amount of air inside the ball and the amount of air outside the ball and within the rectangular box is calculated, what is the difference between the amount of air between these two objects? Convert the answer into cubic inches.

Determine the changes that occur if the rectangular box is full of water. Determine the changes that should be if the rectangular box is filled with water until it reaches the height of 25 cm and the ball floats with 19cm within the waterline and another 19 cm above the waterline.

What happens when the floating ball is taken out of the rectangular box? Changing the amount of water inside the rectangular box to a height of 10 cm causes the weight loss and find out what other changes that occur. In life, one must change accordingly to be in the know of what is happening to the environment, to one.s social unit and also one's house.To make changes happen, one should always gather facts and information to make decisions and strategise so that one could move forward in life. In the box, life is dull, outside the box one face uncertainties, with a filled-up box one could not use it to move on with life, with the ball in the box, one could still use it and have something extra. It depends whether one could enjoy playing with the ball or decide to just do the normal things one use to do. The objective of this question is, a person should be aware of changes and should expect changes anywhere he goes. To manage the changes that occurs needs understanding and the challenges one face needs coaching, mentoring, guidance and actions that produces results. Just examine the parameters given in this quetion and try to relate it to your own environment, your family, your friends and your future. If a month is a box, then a year could be 12 boxess. If the boxes changes every month, there are 120 changes that occurs in a decade.

If your box is wonderful than you you lead a wonderful life. Fulfill your dreams but don't go over your limits. Everyone needs others who have other kinds of boxes in their lives.

ANSWER

Volume of rectangular box = 40 x 40 x 50 = 80000 cm cube ( cm x cm x cm) A sphere have set of all poits in space that have equal distances from the centre of the sphere. So, the ball is considered as the sphere because it has a radius that is of equal distance from the centre of the ball (based on Grolier Encyclopedia ISBN 0-7172-5300-7).

Volume of ball = 4/3 x 22/7 x 19 x 19 x 19 = 28742.476 cm cube

If the thickness of the ball's leather is 8 mm. Then, the volume of air in the ball is

4/3 x 22/7 x (18.2 x 18.2 x 18.2) = 25262.569 cm cube

Then, the amount of air within the rectangular box is

80000 - 28742.476 = 51257.524 cm cube

So, the difference between the amount of air within the rectangular box and the amount of air within the round ball is

51257.524 - 25262.569 = 25994.955 cm cube

1 feet = 12 inches 1 feet = 30.48 cm (based on conversion table) 1 inch = 2.54 cm

1 cubic inch = 2.54 x 2.54 x 2.54 = 16.387 cm cube

So, 25994.955/16.387 = 1586.3156 cubic inches
