Given - Dimensions of brick - 30cm ×10cm ×7 1/2 cm
Dimensions of wall - 30cm long 2m high and 3/4m thick
Find - Number of bricks
Solution - The volume of both brick and wall will be calculated by the formula Length*breadth*height.
Volume of one brick = 30*10*15/2
Volume of one brick = 30*10*7.5
Volume of one brick = 2250 cm³
Now calculating volume of wall. Firstly converting height and thickness into centimetres.
Height = 2 metres
Height = 200 centimetres.
Thickness = 3/4 metres
Thickness = 75 centimetres
Volume of wall = 30*75*200
Volume of wall = 4,50,000 cm³
Number of bricks required = 450000/2250
Number of bricks required = 200
Thus, 200 bricks will be required for given wall.

Step-by-step explanation:
Hey there! :)
Your answer is: Between 11 and 12
11² = 11 × 11 = 121
12² = 12 × 12 = 144
129 is between 121 and 144
Hope this helps :)
