Answer:
The height of the wall is 2.7 m.
Explanation:
The number of blocks required = 2450. Each cubical block has a side of 20cm(0.2m).
But, volume = length × width × height.
So that,
the volume of each block = (0.2 × 0.2 ×0.2)
= 0.008
The total volume of the blocks to be used = 2450 × 0.008
= 19.6
The window has a measurement of 2.5m ×1m;
its space volume = 2.5m ×1m × 0.4m
= 1.0
The door has a measurement of 2m× 3m;
its space volume = 2m× 3m × 0.4m
= 2.4
Thus, the window space and door space has a volume = 1.0 + 2.4
= 3.4
Total volume of the wall = length × width × height
⇒ The total volume of the blocks - the window space and door space volume = length × width × height
The wall to be constructed has a length of 15m and width 40cm (0.4m).
So that the height could be determined as,
19.6 - (3.4) = 15m × 0.4m × height
16.2 = 6 ×height
⇒ height =
height = 2.7 m
Therefore, the height of the wall is 2.7m.
