Question

Mass of a wooden block is 56 g and its density is 800kg/m³ find the volume of block in cm³and m³​

Answer 1

Answer:

➥ The volume of a wooden block = 0.00007 m³ or 70 cm³

Given :

➤ Mass of a wooden block = 56 g

➤ Density of a wooden block = 800 kg/m³

To Find :

➤ Volume of a wooden block = ?

Required Solution :

✒ To find the volume of a wooden block, first we need to convert the mass of a wooden block gram into kilograms, then after we will find the volume of a wooden block.

→ Mass = 56 g

→ Mass = 56/1000

→ Mass = 0.056 kg

Now, we have mass and density of a wooden block,

Mass of a wooden block = 0.056 kg

Density of a wooden block = 800 kg/m³

We can find the Volume of a wooden block by using the formula of volume which says v = m/ρ

Here,

v is the volume in m³ or cm³.

m is the mass in g or kg.

ρ is the density in g/m³ or kg/m³.

✎ So let's find volume of a wooden block (v) ! \:

⇒v = m/ρ

⇒v = 0.056/800

⇒v = 0.00007 m³

Converting m³ into cm³ :

⇒v = 0.00007 m³

⇒v = 0.00007 × 100³

⇒v = 0.00007 × 1000000

⇒v = 70 cm³

║Hence, the volume of a wooden block is 0.00007 m³ or 70 cm³.║
