Question

How many each of volume 600cm cube will be required to construct a wall of 20 m, and 10 m, 30m

Answer 1

Answer:

pls mark me as the brainliest

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
