Dimensions of the oil tin = 26 cm x 26 cm x 45 cm
Total surface area of the sheet = 2(lh + bh + lb)
= 2(26x26 + 26x45 + 26x45)
= 2(676 + 1170 + 1170)
= 2(3016)
= 6032 sq cm
Area of the sheet required to make 20 tins = 6032 x 20 = 120640 sq cm
Total surface area of the sheet = 2(lh + bh + lb)

= 2(676 + 1170 + 1170)
= 2(3016)
