Question
The dimension of an oil tin are 26 m x 26 cm x 45 cm .Find the area of the tin sheet required for making 20 such tins. If 1 square meter sheet costs Rs. 10 , find the total cost for making 20 such tins?
Answer: Option C
- Area of the tin sheet required = Area of 20 oil tins
= 20 × 2 (lb + bh + hl) = 20x2(26x26+26x45+45x26)=12.06m2
Cost of 1 m2 tin sheet = Rs.10
Cost of 12.064 m2 tin sheet = Rs.10 2.064 = Rs.120.64
So, total cost for making 20 such tins = Rs.120.64
