Answer:
Step-by-step explanation:
Given :-
Length of a cuboid = 8 m
Breadth of a cuboid = 12 m
Height of a cuboid = 3.5 m
To Find :-
Total surface area
Formula to be used :-
Total surface area = 2(lb + bh + hl)
Solution :-
Total surface area = 2(lb + bh + hl)
Total surface area = 2(8 x 12 + 12 x 3.5 + 3.5 x 8)
Total surface area = 2(96 + 42 + 28)
Total surface area = 2 x 166
Total surface area = 332 m²
Hence, the total surface area is 332 m²
