Answer:

Height of a cuboid is 3 m

Step-by-step explanation:

Let the height of a cuboid is h m

Given the length of a cuboid is 6 m

The breadth of a cuboid is 5 m

Total surface area of a cuboid is 126 m

2

⟹2(5×6+5×h+6×h)=126

⟹30+11h=63

⟹11h=33

⟹h=

11

33

=3 m

Answer 2

2( lh + hb + lb ) = 208

=> 8h + 6h + 8×6 = 104

=> 14h = 104 - 48

=> 14h = 56

=> h = 4 cm

So, the height of box will be 4 cm. ✔✔
