Question

how many bricks each having length 30 cm 15 cm and height 5 cm are needed to construct 2 wall equal a 6 metre long 6 metre high and 0.25 M tech

Answer 1

Number of bricks=(2×600××600×25)/(30×15×5),

=8000

Answer 2

Answer:

8000

Step-by-step explanation:

Dimension of wall = 6m long

= 6m high

=0.25m thick

Now length of brick= 30 cm => 0.30 m

breath of brick =15 cm =0.15m

height of brick = 5cm =0.05 m

therefore,No. of bricks needed to construct a wall

= vol.of wall

vol. of bricks

=6×6×0.25

0.13×0.15×0.05

=4000

For 1 wall bricks needed=4000

For 2 walls bricks needed=2×4000

= 8000 ANSWER
