You need to convert the liters into cube inches such that:
1 liter = 61.023 cube inches
Hence, evaluating the capacity of jar in cube inches yields:
`6.5*61.023 = 396.6495 ` cube inches
You need to evaluate the number of paper clips that enter into the jar, hence, you need to evaluate n such that:
`n= 396.6495/(2*0.5)~~ 396` paper clips
Hence, evaluating the number of paper clips that enter into the jar yields n = 396 paper clips.
