Surface area of cube = 6*(5)^2
= 150 cm square
Volume of cube = (5)^3
= 125 cm cube
Volume of cuboid = 2.50 * 0.50 * H
Since, cube is melted and recasted into cuboid,
Volume of cube = Volume of cuboid
125 = 2.50*0.50*H
Height of cuboid = 100 cm
Surface area of cuboid = 2*(2.50*0.50 + 0.50*100 + 100*2.50)
= 2*(1.25 + 50 + 250)
= 2*(301.25)
= 602.5 cm square
