how many bricks will be required to build a wall of 8m long , 6m height and 22.5 cm thick, if each brick measures 25 cm by 11.25 cm by 6 cm
Answers
wall;
l=8m=800cm
h=6m=600cm
b=22.5cm
volume of the wall=l*b*
=800*600*22.5
=10800000 cm³
cube
brick;
l=25cm
b=11.25cm
h=6cm
volume=l*b*
=25*11.25*6
=1687.5 cm³
therefore number of bricks=volume of wall/volume of 1 brick
=10800000/1687.5
=6400 bricks
therefore number of bricks is 6400 bricks

Answer:
Step-by-step explanation:
Given :-
Dimensions of Wall :-
Length of wall = 8 m
Height of wall = 6 m
Width of wall = 22.5 m
Dimensions of bricks :-
25 cm × 11.25 cm × 6 cm
To Find :-
Number of bricks
Solution :-
Volume of one brick = (25 × 11.25 × 6) cm³
Volume of the wall = (800 × 600 × 22.5) cm³
Number of bricks = Volume of the walls/ Volume of one brick
Number of bricks = 800 × 600 × 22.5 / 25 × 11.25 × 6
Number of bricks = 6400
Hence, 6400 bricks will be required to build a wall.
