6 less than twice a number is 5

51/2

Step-by-step explanation: 5 = 6 less than 11

Therefor 5 = 6 less than (2 X 5 1/2)

So the number that 5 is 6 less than two of is 5 1/2

One ml is equal to a cm3, then

m=2.67g/cm3*30.5cm3

m=81.435g

If we divide this quantity by 1000 to pass this to Kg we get:

m=81.435/1000=0.081435kg

Step-by-step explanation:

Remember the formula of density is density=mass/volume, if we solve for mass we get:

mass=density*volume
