The bag is given as 68 pounds. We shall start by converting pounds to kilogram. According to the United States metric conversion standards;
![1lb=0.453592\operatorname{kg}]()
That means for every 1 pound, you multiply by 0.453592 to get the equivalent in kilograms. Therefore 68 pounds will be derived as;
![\begin{gathered} 1lb=0.453592\operatorname{kg} \\ 68lb=(68*0.453592)kg \\ 68lb=30.844256\operatorname{kg} \\ 68lb=30.8\operatorname{kg}\text{ (rounded to one decimal place)} \end{gathered}]()
