The rectangular solid has a mass of 3,300 grams.
what is the density of the substance?
with the sides of the cube being 50 cm, 10 cm 30 cm
0.22 g/cm 3
4.5 g/cm 3
36.7 g/cm 3
2.2 g/cm 3

By definition, the density of the substance is given by:

Where,

m: mass of the substance

V: volume of the substance

Calculating the volume of the substance we have:

Then, replacing values we have:

the density of the substance is:

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
