I have 2 problems I need help with. 1. An ice cube measures 12 cm on a side and it floats inwater. 1 cm extends above the water level. If youshaved off the 1 cm part, how many centimeters of the remaining icewould extend above the water level? 2. When a 1.8 kg object is suspended by a scale in water, it"masses" 1.5 kg. What is the density of the object inkg/m3? I have 2 problems I need help with. 1. An ice cube measures 12 cm on a side and it floats inwater. 1 cm extends above the water level.

Explanation / Answer

The relative density is           RD =Weight of the object in air / loss of weight in water               = (1.8 * 9.8 ) / ( 0.3 * 9.8)                = 6 density of the material is          =density of water * RD       water =1000 kg / m3 plug in values
