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
