hi shruthi,

PROCEDURE
Step 1
Here we have to find the total surface area of the cuboidal tank and subtract the roof area as there is no roof

Step 2
Then accordingly find the total cost

SOLUTION
Given

l = 30m
b = 24m
h = 4.5m

Step1
Surface area of tank
= 2(lb+bh+hl)
= 2(30*24 + 24*4.5 + 30*4.5)
= 2(720+108+135)
= 2*963
= 1926 m^2

subtracting the roof area
= 1926 - (l*b) = 1926 - (30*24)
= 1206 m^2

Step2
Cost of iron sheet required
Rate = Rs 65 for 1 m^2
so
Total cost = 65 * 1206 Rs = Rs 78390

Hence the answer is Rs 78390 is the required cost of iron sheets needed to make the tank.

Hope it helped
