The dimensions of an oil tin are 26 cm× 26 cm× 45 cm. Find the area of the tin sheet required for making 20 such tins. If 1 square metre of the tin sheet costs Rs. 10, find the cost of tin sheet used for these 20 tins.

Given,


Dimensions of oil tin are = 26 cm × 26 cm × 45 cm


Then,


Area of tin sheet required for making one oil tin = total surface area of oil tin


=


=


Area of tin sheet required for 20 oil tins =


So,


Cost of 1 m2 tin sheet = Rs. 10


cost of 12.064 m2 tin sheet =
