Kindly check out the below video to learn about the concept of volume of solids. Watch the video till the end to complete the task.
In earlier classes, we have learnt how to find the volume of the basic solids such as cube, cuboid, cone, cylinder, sphere and hemisphere.
Let us recall the formulas to find the volume of the solids mentioned above.

Formula description
|
|
Cube
|
 |
\(a^3\)
|
\(a\) - side |
|
Cuboid
|
 |
\(l b h\)
|
\(l\) - length
\(b\) - breadth
\(h\) - height
|
|
Cone
|
 |
\(\frac{1}{3} \pi r^2 h\)
|
\(r\) - radius
\(l\) - slant height
\(l = \sqrt{r^2 + h^2}\)
\(h\) - height
|
|
Cylinder
|
 |
\(\pi r^2 h\)
|
\(r\) - radius
\(h\) - height
|
|
Sphere
|
 |
\(\frac{4}{3} \pi r^3\)
|
\(r\) - radius |
|
Hemisphere
|
 |
\(\frac{2}{3} \pi r^3\)
|
\(r\) - radius |
