A duck is floating on a lake with 28% of its volume beneath the water. What is the average density of the duck?(adsbygoogle = window.adsbygoogle || []).push({});

This question seems pretty straight froward I realize ultimately that in order to find the answer the duck density= duck mass/duck V. If it is 28% I am assuming that should equal .28V and I know I need to use the formula for bouyant force FB=Weight of fluid=density of fluid x Volume of fluid x g I can plug in the density of fluid but I am not sure how to find all of the other variables having only been given a percentage of the Volume.
