Surface area of a cuboid = 2(lb+lh+bh) = 4150cm square
2(35×25+35h+25h) = 4150
2(875+35h+25h) = 4150
1750+70h+50h = 4150
120h = 4150-1750
h = 2500/120
h = 20.83 cm
2(35×25+35h+25h) = 4150
2(875+35h+25h) = 4150
1750+70h+50h = 4150
120h = 4150-1750
h = 2500/120
h = 20.83 cm

Given Data,
Surface Area of cuboid = 4150 sq. cm
length = 35cm
breadth = 25 cm
height = ? cm
According to the question,
Surface Area of cuboid =2(lb+bh+hl)
2(lb+bh+hl) = 4150
lb + bh + hl = 4150/2
lb + bh + hl = 2075
35×25 + 25h + 35h = 2075
875 + 60h = 2075
60 h = 2075 - 875
60h = 1200
h = 1200/60
h = 20 cm
I hope you have understand.
