Eight squares are needed.
6 sides are needed
Eight, which will be sufficient for 14 squares.
Your square must have sides of 6cm so perimeter is 24cm.
6 squares of the same sizes are needed to build a 3 dimensional cube
6cm + 6cm = 12cm
As there are 10mm in each centimetre, there are (6 x 10) 60mm in 6cm.
