Question

A block of mass 2500kg has volume 5m3 calculate its density in kg/m3 andg/cm 3 in physics​

Answer 1

Given:-

• Mass of block ,m = 2500 Kg

• Volume ,v = 5m³

To Find:-

• Density in Kg/m³ and G/cm³

Solution:-

As we know Density is defined as the mass per unit volume.

• Density = Mass/Volume

• d = m/v

Substitute the value we get

→ d = 2500/5

→ d = 500Kg/m³

Therefore the density of block is 500Kg/m³.

Now Calculating the density into G/cm³

Conversion of Unit

1 kg = 1000g

500 kg = 500 ×1000

And ,

1 m³ = 10⁶ cm³

Density = 500×1000/10⁶

→ d = 500000/1000000

→ d = 0.5 G/cm³

Therefore the density of block in gram centimetre cube is 0.5 G/cm³.
