Formula
surface area of cuboid= sum of srea of all its six rectangular faces= 2(lb + bh + lh)
given
L = 10m
h = 5m
according to question
2(50 + 10b + 5b) = 340
50 + 15b = 170
15b = 120
B = 8m

Step-by-step explanation:
length of cuboid = 10 m
height of cuboid = 5 m
Surface area = 2( lb + bh + hl )
340 = 2 ( 10b + 5b + 50)
170 - 50 = 15b
120/15 = b
So breadth is 8 m
