Volume of sheet = volume of cube
First we will calculate volume of metal sheet =l X b x h
= 27 x8 x1=216cm3
So volume of the cube is also 216 cm3
216=a3
So surface area of sheet = 2(lb+bh+hl)
= 2(27x8+8x1+1x27)
= 502cm2
And surface area of cube
=6a2
=6 x6^2=216cm2
Difference between surface area = 502-216=286cm2
