A block of material has a volume of 50 cubic centimeters, and a mass of 1,000 grams; what is that object's density?

zhannawk [14.2K]

Answer:

Density = $20\ g/cm^3$

Explanation:

Given that,

Mass of the object, m = 1000 g

Volume of the block, V = 50 cm³

We need to find the density of the object. Density is equal to mass per unit volume.

d = m/V

$d=\dfrac{1000\ g}{50\ cm^3}\\\\=20\ g/cm^3$

So, the density of the object is $20\ g/cm^3$ .
