Answer: 1.05 x 10^-2 kg/cm3
Step-by-step explanation:
Given that,
volume of object = 4cm3
mass of object = 42g
Since the standard unit of mass is kilograms, convert 42g to kilograms
(If 1000 grams = 1kg
42 grams = 42/1000 = 0.042kg)
density of object = ?
Recall that density refers to mass per unit volume. So, apply the formula density (p) = mass (m) / volume (V)
p = 0.042kg / 4cm3
p = 0.0105 kg/cm3
Place the value of density in standard form
p = 1.05 x 10^-2 kg/cm3
Thus, the density of the object is 1.05 x 10^-2 kg/cm3
