Question

A student is investigating volume and density.The student has a box, as
shown in Fig. 1.1, a balance, a rule and some dry sand.Fig. 1.1 shows the
dimensions of the inside of the box. The student measures the mass of
the box when empty and when filled with sand. Using the following data
find the density of sand in kg/cubic meter. Write only the numerical value
The figure is given below.

Answer 1

Answer:2200kg/m cube

Explanation:

density=mass/vol.

d=176g/80cm cube

d=2.2 g/cm cube=2200 kg/m cube

Answer 2

Answer:

2.2

Explanation:

volume=4x5x4

mass=216-40=176

density=176/80=2.2g/cm^3
