Explanation: In Psychology, cognitive dissonance is a psychological distress that people experience when they face situations or facts that contradict their beliefs, ideas or values. The cognitive dissonance theory was created by Leon Festinger and suggests that every person in a situation like this becomes uncomfortable and willing to make changes to justify or eliminate the dissonance. There are three ways by which people can reduce this dissonance: reducing the significance of the conflicting beliefs, acquiring new beliefs, or getting rid of the conflicting behavior.
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.
