Step-by-step explanation:
When a sheet the size of 10m×5m is cut into small pieces to the size of 25cm×20cm
how many number of pieces will be cut?
Here’s the strategy you can use:
First, convert meters to centimetersThere are 100 cm in one meter,
somultiply meters by 100 to get similar unitsOut problem now reads:
How many 25cm×20cm pieces can you cut from a 1000cm×500cm sheet?
Now, the problem is much simpler. to solve this problem:
Calculate the area of the full sheet: 1000cm × 500cm = 5000000cm²
Calculate the area of one piece: 25cm × 20cm = 500 cm²
now,Divide one number by the other to get your answer.
so,5000000/500 = 1000
therefore, 1000 piece of paper will get cutted
