Question

24 meters long, 8 meters high and 60 cm 24 cm to make wide wall Long, 12 cm Wide, and 8 cm How many bricks will it take, while 10% of the total volume of the wall is made of a mixture of cement and sand?

Answer 1

Answer:

Step-by-step explanation:

wall;

l=8m=800cm

h=6m=600cm

b=22.5cm

volume of the wall=lbh

                               =800*600*22.5

                               =10800000centi metre cube

brick;

l=25cm

b=11.25cm

h=6cm

volume=lbh

            =25*11.25*6

            =1687.5 centi metre cube

therefore number of bricks=volume of wall/volume of 1 brick

                                             = 10800000/1687.5

                                             =6400 bricks

therefore number of bricks is 6400 bricks
