Question

An open tank is made of iron sheet of 4 m wide.If the dimensions of the tank are 15m*12m*3m,find the cost of iron sheet at Rs 22.50 per m​

Answer 1

Answer:

12112.5

Step-by-step explanation:

iron sheet area = csa (tank) + area(base)

4*L = 2*3(15+12) + (15*12)

4*L= 6(27)+180

4L = 162+180

4L =342

L= 342/4=171/2

cost= 22.5*171/2

=rs 12112.5

Answer 2

Answer:

1222.5

Step-by-step explanation:

4*L = 2*3(15+12) + (15*12)

4*L= 6(27)+180

4L = 162+180

4L =342

L= 342/4=171/2

cost= 22.5*171/2

=rs 1222.5
