Mass of a wooden block is 56g and its density is 800 kg/m³find the volume of block in cm³and m³
Answers
Answer:
In oil the block floats with 60 % of its volume submerged. ... Mass of volume displaced is by object is buoyancy force.
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.║
