Area of the tin sheet required = Area of 20 oil tins
= 20 × 2 (length × breadth + breadth × height + height × length)
Cost of 1 m2 tin sheet = Rs.10
12.064 m2
12.064 × 10
= Rs.120.64
So, total cost for making 20 such tins = Rs.120.64
= 20 × 2 (length × breadth + breadth × height + height × length)
Cost of 1 m2 tin sheet = Rs.10
12.064 m2
12.064 × 10
= Rs.120.64
So, total cost for making 20 such tins = Rs.120.64
