Question

The substance having a density of 0.8g/cm3
has a mass of 64 gram. What is it volume


​

Answer 1

✰ Given :-

• The substance having a density of 0.8g/cm3 has a mass of 64 gram .

✰ To find :-

• Volume substance

✰ Solution :-

• Density of substance = 0.8 g/cm³

• Mass of substance = 64 g

As we know that:-

• → D = m/V

• Where " D " is density, " m " is mass and " V " is volume of substance.

According to question:-

• → Density = Mass/Volume

• → 0.8 = 64/V

• → 8/10 = 64/V

✰ Cross multiplication ✰

• → 8 × V = 10 × 64

• → 8V = 640

• → V = 640/8

• → V = 80 cm³

Hence,

• Volume of substance is 80cm³

✰ More to unit ✰

• C.G.S unit of density is g/cm³

• S.I unit of density is kg/m³

Answer 2

Answer:

80 cm3

Explanation:

Density = 0.8g/cm3

Mass = 64 gram

As you now density = mass/volume

To find volume

so, volume = mass/density

volume = 64/0.8 = 80

so, volume = 80 cm3
