1 point
7 kg/m3
2 kg/m3
2.5 kg/m3
60 kg/m​

Answer 1

Given:-

• Mass of metal iron box (m) = 350kg

• Volume (v) = 175m³

To Find:-

• Density of metal iron box (d).

Solution:-

As we know that ,

⟹ Density = Mass/Volume

⟹ d = m/v

Put the value which is given above

⟹ d = 350/175

⟹d = 2kg/m³

∴ The density of metal iron box is 2kg/m³

Additional Information!!

✧ Mass per unit volume is called Density of the object.

✧ SI unit of Density kg/m³

✧ The space occupied by a solid body is called its volume.

✧ SI unit of Volume is m³.

Answer 2

Aɴsᴡᴇʀ :

➥ The density of metal iron box = 2 kg/m³.

Gɪᴠᴇɴ :

➤ Mass of metal iron box (m) = 350 kg

➤ Volume of metal iron box (v) = 175 m³

Tᴏ Fɪɴᴅ :

➤ Density of metal iron box (d) = ?

Sᴏʟᴜᴛɪᴏɴ :

$\sf{: \implies Density = \dfrac{Mass}{Volume}}$

$\sf{: \implies Density = \dfrac{350}{175} }$

$: \implies \green{\underline{ \overline{ \boxed{ \purple{ \bf{ \: \: Density =2 \: kg/{m}^{3} \: \: }}}}}}$

Hence, the density of metal iron box is 2 kg/m³.

Additional Information :

Some releted formula

⪼ $\sf{Density = \dfrac{Mass}{Volume}}$

⪼ Mass = Density × Volume

⪼ $\sf{Volume = \dfrac{Mass}{Density}}$

Density :- The amount of mass per unit of volume of an object or substance. Measured in units of g/cm³ or g/mL.

Mass :- The amount of matter that an object or substance contains.

Measured in units of Grams (G).

Volume :- The amount of space measured in a cubic units that an object or substance occupies.

Measured in units of cm³ or mL.
