Question 2

The table gives the mass and the volume of three objects $X$ , $Y\,$ and $Z$ .

Object	Mass ( $g\text{g}$ )	Volume ( $cm3\text{cm}^3$ )
$X$	135	150
$g\text{g}$	48	80
$Z$	210	300

Which objects can float in a liquid of density 0.75 g/cm³?

$X$ and $Y$ only

$Y$ and $Z$ only

$X$ and $Z$ only

$X$ , $Y$ and $Z$
