The block factory has boxes to pack groups of one hundred blocks. if maks has an order for 2,340 blocks, how can he pack them using the fewest packages?

The factory has available of boxes that packs 100 blocks.
Maks ordered 2 340 blocks.
Now, how many packs will he have using the fewest packages which is 100.

=> In every 1000, there would 10 boxes with every 100 blocks per box
=> in 2 000, there would a total of 20 boxes
=> plus 300 blocks, that would be another 3 boxes
=> plus 40 blocks, can be placed on 1 box
=> 20 boxes with 100 blocks each + 3 boxes with 100 blocks each and 1 box with 40 blocks
=> 23 boxes with 100 blocks each and 1 box with 40 blocks
=> 24 boxes in all with 2 340 blocks inside.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
