Three solids a square pyramid, a cone and a sphere have been carved out from three solid cubes of the same size. Find the volume of each solid. |

Answer» Volume of square pyramid = \(\frac{1}{3}\) a3 Volume of cone = \(\frac{1}{3}\pi (\frac{a}{2})^2\times a=\frac{1}{3}\times\pi\frac{a^3}{4}\) = \(\frac{1}{12}\pi a^3\) Volume of sphere = \(\frac{4}{3}\pi\times(\frac{a}{2})^3\) = \(\frac{4}{3}\pi\times\frac{a^3}{8}=\frac{1}{6}\pi a^3\) |
