Answer:
125.55 m.
Stepbystep explanation:
We need to find the volume of the bricked wall.
= total volume  volume of the windows  volume of the gateway.
= 4 * 0.4 * L  2 * 2.5 * 1 * 0.4  2 * 3 * 0.4 m^3. (where L is the length of the wall).
Also this volume = number of bricks * volume of 1 brick
= 24560* 0.2^3.
So
4 * 0.4 * L  2 * 2.5 * 1 * 0.4  2 * 3 * 0.4 = 24560* 0.2^3
1.6L  2  2.4 = 196.48
1.6L = 200.88
L = 125.55 m.
