Answer:
120640cm²
Step-by-step explanation:
Given :-
Dimensions of an oil tin are 26cm×26cm×45cm
length = 26cm
breadth = 26cm
height = 45cm
Total surface area of oil (cuboid) tin
= 2( lb+bh+hl)
= 2(26×26+26×45+45×26)
= 2(3016)
= 6032
The total surface area of one tin = 6032cm²
So, the total surface area of 20 such tins = 6032×20 = 120640cm²
