Question

A wall of length 25m breadth 64cm and height 2m is to be constructed by using bricks ,each dimension 20cm×10cm×8cm.how many bricks will be needed to construct the wall

Answer 1

Hi friend ✋✋✋✋
--------------
Your answer
--------------------

Dimensions of a wall : -

Length = 25 m = 2500 cm

Breadth = 64 cm

Height = 2 m = 200 cm


Dimensions of each of the bricks used = (20 cm × 10 cm × 8 cm)

Then,
----------

Number of bricks needed to construct the wall = (2500 × 64 × 200)/(20 × 10 × 8) = 20000 bricks

HOPE IT HELPS

Answer 2

hiii!!!

here's ur answer...

given the Length of the wall = 25m

breadth of the wall = 64cm = 0.64m

height of the wall = 2m

volume of the wall = l × b × h

= 25 × 0.64 × 2

= 32m³

now,

length of the brick = 20cm = 0.2m

breadth of the brick = 10cm = 0.1m

height of the brick = 8cm = 0.08m

volume of the brick = l × b × h

= 0.2 × 0.1 × 0.08

= 0.0016m³

$hence \: number \: of \: bricks \: required \: to \\ construct \: the \: wall = \frac{32}{0.0016} = 20000 \\ \\ 20000 \: bricks \: are \: required. \\ \\ hope \: this \: helps \: you...$
