Question

an iron object has volume of 25 cm cube and the density of iron is 7.87 gram centimetre cube. what is the mass of the object?

Answer 1

Answer:

196.75 gram

Step-by-step explanation:

Formula to find mass of an object=  density* volume

Therefore, mass of the object= 7.87*25 gram

=> m= 196.75 gram

Answer 2

Given

An iron object has volume of 25 cm cube and the density of iron is 7.87 gram centimetre cube

To find

What is the mass of the object?

Solution

• Volume of iron = 25cm³
• Density of iron = 7.87 gm/cm³
• Mass = ?

$\implies\sf Density =\dfrac{Mass}{Volume} \\ \\ \\ \implies\sf Mass =Density\times{Volume} \\ \\ \\ \implies\sf Mass = 7.87\times{25} \\ \\ \\ \implies\sf Mass = 196.75 gm$

Hence, the mass of iron is 196.7gm
