Answer:

4.61m

Step-by-step explanation:

Total number of Bricks = 4700

Dimensions of bricks = 25cm×16cm×10cm

Dimensions of Wall = 20m long, 20cm wide, height = ?

Dimensions of windows = 2m×1.5m

number of windows = 2

volume of 2 windows = 2×1.5×2×1.5×0.2×0.2

= 4×2.25×0.2×0.2

= 0.36 m

Volume of Wall = 4700×[25×16×10]

= 4700×400

= 18800000 cm³ = 18.8 m³

= 18.8 - 0.36

= 18.44 m³

height of wall = 20×0.2×h = 18.44m

= 4×h = 18.44

= h = 18.4414

= h = 4.61 m

Therefore height of wall is 4.61 m.
