Question

The no.of bricks to be laid in a square field of side 30cm if the side of each brick is 3 cm, is

Answer 1

1000 bricks
As, Area of field =30*30*30=27000
Area of one brick =3*3*3=27
No. Of bricks =27000/27
=1000

Answer 2

The number of bricks is 1000

Step-by-step explanation:

As the given problem mentions about the square field, let us assume that length, breadth, and height of the brick is same.

$\mathrm{ Area \ of \ the \ square \ field \ of \ side \ 30 \ cm}=30 \times 30 \times 30=27000 \ cubic \ cm$

$\text{ Area of the brick of side 3 cm}=3 \times 3 \times 3=27 \text { cubic } \mathrm{cm}$

Now,

$\text{Number of bricks}=\frac{\text {Area of } 30 \mathrm{cm} \text { square field }}{\text { Area of 3 cm square }}$

$=\frac{27000}{27}$

$\therefore \text { Number of bricks }=1000$

Therefore, 1000 bricks to be laid in a square field of side 30 cm.
