Answers
Answer:
5.56 m²
Rs.83.40
Step-by-step explanation:
We are assuming that the oil tin will be closed from the top, like a standard oil tin.
The six sides of the oil tin will have dimensions:
15cm x 8cm (2 sides)
15cm x 25 cm (2 sides)
8cm x 25cm (2 sides)
The total surface area of 1 oil tin will be:
= 2*(15*8 + 15*25 + 8*25) cm²
= 2*(120 + 375 + 200) cm²
= 2*(695) cm²
= 1390 cm²
=> The total surface area of 1 oil tin = 1390 cm²
=> The total surface area of 40 oil tins = 40*1390 = 55600 cm²
Now,
1m = 100 cm
1m² = 100 cm * 100 cm
1m² = 10000 cm²
1 cm² = (1/10000) m²
55600 cm² = 55600/10000 = 5.56 m²
Answer: 40 oil tins will need 5.56 m² of tin sheet
Cost of tin
The cost of tin is given to be Rs.15 per m²
=> 1 m² will cost Rs.15
=> 5.56 m² will cost Rs.(15*5.56) = Rs.83.40
Answer: 40 oil tins will need tin worth Rs.83.40

=> The total surface area of 40 oil tins = 40*1390 = 55600 cm²
Now,
1m = 100 cm
1m² = 100 cm * 100 cm
1m² = 10000 cm²
1 cm² = (1/10000) m²
55600 cm² = 55600/10000 = 5.56 m²
Answer: 40 oil tins will need 5.56 m² of tin sheet
Cost of tin
The cost of tin is given to be Rs.15 per m²
=> 1 m² will cost Rs.15
=> 5.56 m² will cost Rs.(15*5.56) = Rs.83.40
Answer: 40 oil tins will need tin worth Rs.83.40
