Question

Mass of cube is 210g . If one side of the cube is 3 cm . What is density of the cube

Answer 1

mass /volume..

210/3=g/cm cube...

Answer 2

Hey mate!

Here's your answer!

It is given that,

m = 210g = 0.210kg; side, a = 3cm = 0.03m

Now,

Volume of cube =

$a {}^{3}$

$= > (0.03) {}^{3}$

$= > 0.000027 \\ = > 27 \times 10 {}^{ - 4} m {}^{3}$

We know that,

Density = Mass/Volume

$(210 \times 10 {}^{ - 3} ) \div (27 \times 10 {}^{ - 4} ) \\ = > 7.7 \times 10 \\ = > 77kgm {}^{ - 1}$

Hope it helps :)
