Answer» ANSWER: Rs . 6400 is the cost of iron required Step-by-step explanation: Length l=12m Breadth b=9m Height h=4m ⇒ TOTAL surface of the TANK =2(l×b+b×h+h×l) =2(12×9+9×4+4×12) =2×(108+36+48) =192×2 =384m2 ⇒ Length of the SHEET required =384 / 1.5 =256 m ∴ Cost of the sheet =256×25 =Rs .6400 ∴ Total cost of the sheet =Rs.6400 Hence, the answer is Rs. 6400

Answer»

ANSWER:

Rs . 6400 is the cost of iron required

Step-by-step explanation:

Length l=12m

Breadth b=9m

Height h=4m

⇒ TOTAL surface of the TANK =2(l×b+b×h+h×l)

=2(12×9+9×4+4×12)

=2×(108+36+48)

=192×2

=384m2

⇒ Length of the SHEET required =384 / 1.5

=256 m

∴ Cost of the sheet =256×25

=Rs .6400

∴ Total cost of the sheet =Rs.6400

Hence, the answer is Rs. 6400
