Question

Calculate the volume of a wooden object of mass 280kg, if its density is 800kg/m3 .​

Answer 1

Answer:

Provided that:

• Mass = 280 kg
• Density = 800 kg/m³

To calculate:

• Volume

Solution:

• Volume = 0.35 m³

Using concept:

• Volume formula

Using formula:

• ${\small{\underline{\boxed{\pmb{\sf{Volume \: = \dfrac{Mass}{Density}}}}}}}$

Required solution:

$:\implies \sf Volume \: = \dfrac{Mass}{Density} \\ \\ :\implies \sf Volume \: = \dfrac{280}{800} \\ \\ :\implies \sf Volume \: = \dfrac{28}{80} \\ \\ :\implies \sf Volume \: = \dfrac{14}{40} \\ \\ :\implies \sf Volume \: = \dfrac{7}{20} \\ \\ :\implies \sf Volume \: = 0.35 \: m^3$
