Surface Area of cuboid =2(lb+bh+hl)

Surface Area of cuboid = 758 sq. cm ( given )
length = 14 cm 
breadth = 11 cm 
height = ? cm 

ATQ 

2(lb+bh+hl) = 758

lb + bh + hl = 758/2

lb + bh + hl = 379

14 x 11 + 11h + 14 h = 379

154 + 25h = 379 

25 h = 379 - 154
 
25h = 225

h = 225/25 

h = 45/5

h = 9 cms.

hope this helps you out!
