Answer 2

Answer: The total area of four walls is 400 m²

Step-by-step explanation:

Since, a hall is in the form of a cuboid of edges 15 m, 10m and 8m.

⇒ The cuboid has,

Length, l = 15 m

Width, w = 10 m

And, height, h = 8 m

Thus, the area of the four walls = 2 × l × h + 2 × w × h

= 2 × 15 × 8 + 2 × 10 × 8

= 240 + 160

= 400 m²
