A circular well with a diameter of 2 metres, is dug to a depth of 14 metres. What is the volume of the earth dug out?

Given that,

Diameter of the circular well = 2 m

Radius = 1 m

Height = 14 m

Therefore,

Volume of cylindrical well =

= × 1 × 1 × 14

= 44 m³

Hence, option D is correct

Three cubes of iron whose edges are 6 cm, 8 cm and 10 cm respectively are melted and formed into a single cube. The edge of the new cube formed is

Five equal cubes, each of edge 5 cm, are placed adjacent to each other. The volume of the cuboid so formed, is
