Question

How many bricks each of dimensions 25cm*16cm*10cm will be needed to build a wall of 24m long 6m high and 0.4 thick? what is the cost of the bricks at the rate of rs. 2000 per hundred bricks?

Answer 1

Answer:Number of bricks needed = 14400

Step-by-step explanation:

Dimensions of each brick:

l×b×h = 25 cm × 16 cm × 10 cm

Dimensions of the wall:

Length (L) = 24m = 2400cm,

Breadth (B) = 6m = 600 cm

Height (H) = 0.4 m = 40m

L × B × H = 2400 × 600 × 40

Let number of bricks needed = n

n= volume of wall/volume of brick

n=L*B*H/l*b*h

n=2400 × 600 × 40/25 cm × 16 cm × 10 cm

n=14400

Therefore,

Number of bricks needed = 14400
