2(lb+bh+lh)=4150
35x25 + 25 x h + 35 x h = 2075
875 + h(25+35) = 2075
60h = 12000
h = 20cm

Surface area of cuboid = 4150 cm^2
=> 2(lb+bh+lh ) = 4150 cm^22
=> 2 (35 x 25 +25h + 35h ) = 4150 cm^2
= >1750 + 25h + 35h = 4150 cm^2
=> 5h (5 + 7) = 4150 - 1750
=> 5h x 12 = 2400
=> 5h = 2400 ÷ 12 cm
=> h = 200 ÷5 cm
so, h = 40 cm
