Answer 2

Answer:

The answer is option 4.

Explanation:

Firstly, you have to convert the mass of tea bagto kilogram as the question wants the unit in kg/m³.

$1000g = 1kg$

$100g = 1kg \div 10$

$100g = 0.1kg$

So the mass of tea bag is 0.1 kg. Next you have to use density formula ρ = mass/volume. Then you have to substitute the values into the formula :

$ρ = \frac{mass}{volume}$

Let mass = 0.1kg,

Let volume = 0.025m³,

$ρ = \frac{0.1}{0.025}$

$ρ = 4kg \: per \: {m}^{3}$
