Question

calculate the density of an object having mass of 20g having the length of 2cm,

breadth of 2cm and height of 1cm. also pridict whether this object will float or sink in water.​

Answer 1

Answer:

m = 20 g

v = 2 x 2 x 1 = 4 cm³

D = m/v

D = 20 / 4

D = 5 g/cm³

Density of water is 1 g/cm³ so this object will sink.

Answer 2

Answer:

5g/cm³

Explanation:

m=20g

l=2cm, b=2cm, h=1cm

v=lbh=2x2x1cm³=4cm³

density=20/4=5g/cm³
