Question

16. The length of a cold storage is double its breadth. If its height is 3 m and the area of its four walls is 108 m, then its length and breadth are
O (a) 14 m and 7 m
O (b) 12 m and 6 m
O (c) 16 m and 8 m
O (d) 18 m and 9 m​

Answer 1

Given,

l=2b and h=3 m

Now, Area of four walls = 108 m  

3

 

2(l+b)h=108

18b=108

b=6 m

Therefore, l=2b=12 m

Hence, volume of the cold storage = lbh=12×6×3=216 m
