surface area of a cuboid = 2(lb+BH+hl)
= 2(25×18+18×14+14×25)
= 2(1052)
= 2104
surface area of a cuboid is 2104 cm^2
Hope it helps

Surface area of a cuboid = 2(lb+ bh+ lh)
= 2(450+ 252+350)
=2(1052)=2104
As the bor was opened =lb = 25×18 =350
surface area of the box =2104- 350=1754cm^2
= 2(450+ 252+350)
=2(1052)=2104
