Question

the volume of 500g sealed packet is 750 cm3 will the packet float or sink ?

Answer 1

According to Archimedes principle-

$\blue{\boxed{Object\: floats\: only\: when\: it's \:density ≤ density\: of\: fluid}}$

First we have to calculate it's density-

$density = \frac{mass}{volume} \\ \frac{500}{750} \\ \\ 0.67gm {cm}^{ - 3}$

Taking fluid as water

$fcolorbox{red}{yellow}{Density\:of \:water\:is\:1gm/cm^3}$

So,
