You have two pieces of string. One is 8 cm long. The other is 20 centimeters long. You want to cut each piece if string into sma

Minchanka [31]

ah, basically what length can you divide each string to get a certain length

factor each

8=2*2*2

therefor:

8=1*8=2*4=4*2=8*1

so you can have 1 length of string 8cm long

2 lengths of string 4cm long

4 lengths of string 2cm long

8 lengths of string 1cm long

20cm string

factor

20=1*2*2*5

so 20=1*20=2*10=4*5=5*4=10*2=20*1

you can have 1 string 20cm long

2 strings 10cm long

4 strings 5cm long

5 strings 4cm long

10 strings 2cm long

20 strings 1cm long

we need greatest common length

in 8cm stirng, we have 1,2,4,8

in 20cm string, we have 1,2,4,5,10,20

greatest common length is 4

answer is 4cm

alternately, you could have done this:

8=2*2*2

20=2*2*5

common grooup is 2*2=4 so 4 is answer

You have a 10×10×10 inch cube that is made up of 1×1×1 inch cubes. You paint the outside of the big cube red. How many of the li

natima [27]

The total amount of little cubes on the surface is 600, since there is 100 cubes on one face and there are 6 faces (6 times 100). But, there is overlap because the cubes on the edges are painted on more than one edge. There are 12 edges, and every edge has 10 that need to be subtracted. So that’s a total of 120 that need subtracting, and 600-120 is 480.
