A cube whose volume is 1/8 cubic centimetre is placed on top of a cube whose volume is `1\ c m^3dot` The two cubes are then placed on top of a third cube whose volume is `8\ c m^3dot` The height of the stacked cubes is (a) 3.5 cm (b) 3 cm (c) 7 cm (d) none of them

Explanation

Volume of cube = `side^3`

Here, Volume of first cube = `1/8cm^3`

`S^'=1/8^3`

`S^'=1/2cm`

Volume of second cube = `1cm^3`

`S^''=1cm`

Volume of third cube = `8cm^3`

`S^'''=2cm`
