Question

5 stars for best answer

Answer 1

The answer is 22K/cubic ft

Answer 2

$\rho = \frac{m}{V}$

where ρ is the density, m is the mass, and V is the volume.

*********************************************************

We have
v = 60
m = 1320
$\rho =?$


$\rho = \frac{m}{V} \\\\\rho = \frac{1320}{60}\\\\\rho = 22$


The density of the pile is 22 kg/cf
