what is the density of a block whose mass is 45 g and has a volume of 15 cm3
3 g/cm3
675 g/cm3
30 g/cm3
0.333 g/cm3

Explanation:

Step1: Recall density formula

$
ho=\frac{m}{V}$ (where $
ho$ is density, $m$ is mass, $V$ is volume)

Step2: Substitute values

$m = 45$ g, $V=15$ cm³, so $
ho=\frac{45}{15}$

Step3: Calculate result

$\frac{45}{15}=3$ g/cm³

Answer:

A. 3 g/cm3
