Height of cuboid is 7 cm
Area of four walls is 378 cm²

Breadth of a cuboid
Step-by-step explanation:
Let the length be l, the breadth be b, and height be h.
Area of 4 walls of a cuboid is 2(l + b) × h
Now, 2(l + b) × h = 378
- 2(15 + b) × 7 = 378
- 30 +2b =
- 2b =
- 2b = 54 - 20
- 2b = 34
- b= 17
So, the breadth of the cuboid is 17 cm.
