Length = 12

Breadth = 10

Height = 8

Lateral Surface Area of Cuboid = 2 * h * (l + b)

Lateral Surface Area of Cuboid = 2 * 8 * (12 + 10)

Lateral surface area = 352

Total Surface Area of Cuboid = 2 * (l * b + b * h + l * h)

Total Surface Area of Cuboid = 2 * (12 * 10 + 10 * 8 + 12 * 8)

Total surface area = 592
