Questions 1 : The king’ s Elephant ProblemOnce upon a time the King of Siam asked his worriorsto measure the weight of an elephant. However theweight of the elephant was too heavy to be measuredby the biggest weighting machine avaible. Help theworriors to solve the problem.
Identify the problemmeasure the weight of an elephantthe weight of the elephant was too heavy to bemeasured by the biggest weighting machine avaibleHelp the worriors to solve the problem
Draw the diagram ( chose strategy ) Cut the elephant into a part Measure the weights of all parts of elephant x + x + x + x + x = 5x kg ( Elephant )
Water displacementThe elephant = volume of water displecement
Using Equations (checking answer) Density = mass ( kg ) volume Let says density of water = 1 kg per liter Volume of water desplacement = 1000 liter 1 kg liter = X 1000 liter 1000 kg = x
Questions 2 : Abu Nawas’ Problem In one of the stories in ‘One Thounsand and One Night’. Abu Nawas would only allow any traveller to fetch water from the only well in the desert after solving the following problem: The travellers were given a 3-liter container and a 5- liter container. They have to measure exactly four and seven litres of water using the above containers. You are required to help the travellers solve the problem.
Identify the problemThe travellers were given a 3-liter container and a 5-liter container.They have to measure exactly four and seven litres ofwater using the above containers.Help the travellers solve the problem
Draw the diagram ( chose strategy ) 5 liter container 3 liter containerNow, pour the water into a containers to get 4 liter and7 liter using above containers.
To get 4 liters of water ( carry out the strtegy)1 litres + 3 litres = 4 litres 4 litres + 0 liters = 4 litres
To get 7 litres of water 5 litres + 2 litres = 7 litres 4 litres + 3 litres = 7 litres
Using formulaEquations To get 7 litresLets say 3 litre – x Y+(y–x)=7Lets say 5 litre – y Y+(5-x)=7To get 4 litre To get the(y–x)+(y–x)=4 answers, subsititue x and 2(y –x ) = 4 y into the equations.
Act the situation ( checking answer ) See carefully and try to understand ^_^
