3 × 3 = 9 m ❤️

Answer 2

Answer:

Number of bricks required to construct a 1 brick thick wall having length 3 m and height 3 m is 450.

Step-by-step explanation:

• The concept used in the counting number of the bricks is the Surface area..
• The length of the wall is 3m
• The height of the wall is 3m
• The area of the wall facing= $3\times3=9m^2$

                                                     =90000cm²

• The size of the brick is 10cm x 10cmx 20cm
• The dimension facing the brick is 10cm x 20cm.
• The area of the brick=200cm²
• Number of bricks is given by the ratio od the surface area of the wall to the surface area of the brick.

        $N=\frac{Surface\ area \of \ wall}{Surface\ area \of \ wall}\\ N=\frac{90000}{200}\\ N=450 bricks$
