Answer 2

Answer:

The total surface area of cuboid is 126 m².

Step-by-step explanation:

Total surface area of cuboid =2(lb+bh+lh)

Height=3 m

Length= 5 m

Breadth=6 m

According to the formula=2(5 x 6 +6 x 3+5 x 3)

                                         = 2(30+18+15)

                                         = 2(30+33)

                                         =2(63)

                                         =126 m²
