Length of the tank = L = 12 m 
Breadth of the tank = B = 8m 
Height of the tank = H = 6 m 
Area of the Lateral surface = 2*(L + B)*H = 2*(12 + 8)*6 m^2 = 240 m^2 
Area of the Base = L*B = 12*8 m^2 = 96 m^2 
Total Surface Area of the open tank = (240 + 96) = 336 m^2 = Area of the iron sheet required = A 
width of the iron sheet = W = 4 m 
Length of iron sheet required = A / W = 336 / 4 m = 84 m 
Cost of iron sheet per meter = Rs17.50 
Cost of 84 m of iron sheet = Rs 17.50 * 84 = Rs 1470

Answer 2

Answer:

Step-by-step explanation:

Here, l=12m, b=8m,h=6m. We know that,

There fore, lbh=(12. 8. 6)m

=576m ans/
