Question

how many bricks will be required to construct a wall 10m long,4dm wide and 3m high,if each brick measures 25cm×12cm× 8cm.​

Answer 1

Answer:

2400

Step-by-step explanation:

25 x 12 x 8 = 2400

25 x 12 x 8 = 2400

25 x 12 x 8 = 2400

25 x 12 x 8 = 2400

25 x 12 x 8 = 2400

Answer 2

height of wall=10 m

breadth=3m

length=4m

volume=l×b×h

=1000×400×300=120000000cu cm[converted in cm]

now volume of one brick=25×12×8=2400cu cm

bricks needed to construct wall=volume of wall/volume of brick

=120000000/2400=50000 bricks needed to construct the wall
