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.
Solid | Figure | Volume (in cubic units) | 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 |
