Answer:
length = 7cm
breadth = 0.57dm so it will be 5.7cm(1 dm= 10cm)
height = 0.14 m = 140cm
surface area =2(l*b+b*h+h*l)
2(7*5.7 + 5.7*140 + 140*7)
2(39.9 +798+980)
2 *1817.9
3635.8 cm 2

Area of cuboid = 2(lb + bh + hl)
= 2(7×5.7 + 5.7×140 + 140×7)
= 2(39.9 + 798 + 980 )
= 2(1817.9)
= 3635.8 cm^2
