Question

The dimensions of a solid is 10cm x 10cm x 10cm. If the mass of the solid is 600 g
Find the density of the solid in (a) g/cm3 (b) kg/m3.

​

Answer 1

Answer:

Explanation:

Dimensions of solid are 10cm*10cm*10cm

Therefore the solid is a cube as all the dimensions are equal

That is the volume of cube =s^3=10^3=30 cm^3

Mass of the solid is given as 600g

To find: density of solid in (a) g/cm^3 (b) kg/m^3

(a) density =mass/volume

Let density be x

x =600/30

x=20 g/cm^3

(b) 1m =100cm

10 cm = 10/100 =1/10 m Therefore m^3 = (1/10)^3= 1/1000 m^3

1 kg=1000 g

600g = 600/1000=6/10 kg

Let Density be y

y=6/10/1/10 = 6 kg / m^3
