Answer:
5m
Step-by-step explanation:
given LSA = 130m^2
length=7m
breadth=6m
let height be x
therefore 2h (l+b) =130
= 2x (l+b) =130
= 2x (7+6)
= 2x (13)
= 26x = 130
= x = 130/26
= x= 5m
height = 5m

Answer:
Step-by-step explanation:
Total surface area = 2( Surface area of base ) + (Surface area of 4 walls)
40=2(S)+26
2S=14
S=7 m 2
Hence, surface area of base is 7 m 2 .
