Question

find the density of a block with mass = 150g and volume = 30cm³
120 g/cm³
100 g/cm³
4.5 g/cm³
5 g/cm³

Explanation:

Step1: Recall the density formula

Density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume.

Step2: Substitute the given values

Given $m = 150g$ and $V=30cm^{3}$. Substitute into the formula: $
ho=\frac{150}{30}$.

Step3: Calculate the density

$\frac{150}{30}=5g/cm^{3}$.

Answer:

$5g/cm^{3}$ (the fourth option)
