Solution

Correct option is (a) 6cm

Given, a metal sheet 27cm long, 8cm broad and 1cm thick.
Then, volume of the sheet (cuboidal) =l×b×h
=27×8×1=216 cm3
Now, since this sheet is melted to form a cube of edge length a (say).
Then, volume of the cube = Volume of the metal sheet
a3=216cm3
a=6 cm
Hence, the side of the cube is 6cm.
