Solution

$v o l u m e equals 3 m cubed M a s s equals 9 k g D e n c i t y space o f space s u b s tan c e equals fraction numerator m a s s space o f space s u b s tan c e over denominator v o l u m e space o f space s u b s tan c e end fraction D e n c i t y space o f space s u b s tan c e equals 9 over 3 equals 3 space bevelled fraction numerator k g over denominator m cubed end fraction a n d space d e n c i t y space o f space w a t e r equals 1000 space bevelled fraction numerator k g over denominator m cubed end fraction t h e space o b j e c t space w i l l space f l o a t space i n space t h e space w a t e r space a s space t h e space d e n c i t y space o f space t h e space o b j e c t space i s space l e s s space t h a n space t h e space d e n c i t y space o f space w a t e r space$
The object will float in the water as the density of the object is less than the density of water.
