Question

a) A block of mass 150 kg has a volume of 3m3

. Calculate its density in (a) kg m-3

(b) g cm-3​

Answer 1

Answer:

a. Density = Mass/Volume

= 150/3

= 50 kg/m³

b. 1 kg = 1000 g

150 kg = 150000 g

Density = Mass/Volume

= 150000/3

= 50000 g/m³

Answer 2

Answer:

a) 50 kg/m³

b) 0.05 g/cm³

Explanation:

Given:

• Mass = 150 kg

• Volume = 3 m³

To find:

• Density

Method to find:

$Mass = Volume * Density$

⇒ 150 = 3 * Density

⇒ Density = 150/3 = 50 kg/m³

__________________________________________________________

$1 kg/m^3 = 0.001 cm/g^3$

⇒ 50 kg/m³ = (0.001 * 50) g/cm³

⇒ 50 kg/m³ = 0.05 g/cm³

Hope it helps!
