Answer:

$\huge\boxed{\fcolorbox{blue}{yellow}{Answer:}}$

The answer is 40 cm³

Density is mass in grams over volume in cubic centimeters. So it is :-

2000g/50cm³ = 40cm³

The unit is grams per cubic centimeter.

NB - density can also be kilograms over cubic meters

Answer 2

Given :

→ Mass of an object is 2000g and its volume is 50cm cube

To find :

→ Density of the object

Explanation :

First we have to convert the given units into S.I units

2000g = 2kg Mass

50cm cube = 5.0 × 10^-5 m cube

Now the Density of the object :

$density = \frac{mass}{volume} \\ density = \frac{2kg}{5 \times 10 {}^{ - 5}m {}^{3} } \\ = 0.000025 \: kg \: per \: m {}^{3} \\ = 25 \times 10 {}^{ - 6} kg \: per \: m {}^{3}$
