Question

2. An iron block weighs 23.4 kg. Its volume is found to be
3000 cm'. Find its density in g/cm and in kg/m'.​

Answer 1

Answer:

it is simple. first change 23.4 kg in gram and write 3000cm.

next, change 3000cm into m and write.

Answer 2

The density is g/cm³ and kg/m³ is 7.8 and 7800 respectively.

Given - Mass and volume

Find - Density

Solution - As we know, 1000 gram = 1 kg and 100 cm = 1m.

So, mass in grams = 23.4*1000

Mass in grams = 23400 grams.

Volume in m³ = 3000/10⁶

Volume in m³ = 0.003

Density in g/cm³ = $\frac{23400}{3000}$

Density in g/cm³ = 7.8

Density in kg/m³ = $\frac{23.4}{0.003}$

Density in kg/m³ = 7800

Hence, density in g/cm³ and in kg/m³ is 7.8 and 7800 respectively.
