Question

Please answer the above ​

Answer 1

Answer:

Density = Mass/volume

16000÷8000

=2

Answer 2

Answer:

2

Explanation:

Given:

• Mass of the cube (M) = 16 kg = 16000 g

• Side of the cube = 20 cm

So, volume of the cube (V) = 20³ =  8000 cm³

To find:

Density (d)

Method to find:

M = Vd

⇒ 16000 g = 8000 cm³ * d

⇒ d = 16000 g/ 8000 cm³  

⇒ d = 2 g/cm³

Relative density  = Density of substance / Density of water

⇒ 2 g/cm³ / 1 g/cm³

⇒ 2

(relative density has no unit as it compares quantities of similar unit)
