A container is partially filled with water. A scale on the wall indicates that the volume of

water is $312$ cm

$3$

$.$ The weight of water and container is $568$ gram. Some sand is carefully

poured into the water. The water level in the container rises to a level that it contains $400$

cm

$3$ of material $($sand and water$).$ The weight of the container now is $800$ gram. Determine

the density of the particle material, in kg$/$m

$3$

$.$ Some measurements showed that $60$ cm

$3$ of

water was still above the sand level. Determine the density of sand placement in the

container, in kg$/$m

$3$

$.$ Weight of the container was found to be $245$ grams.
