Calculate the number of bricks, each measuring 25 cm x 15 cm x 8 cm required to construct a wall of dimensions 10 m x 4 m x 5 m when 10% of its volume is occupied by concrete ?  Pick one:  A) 6000  B) 5400  C) 3800  D) 4700  E) 2500
Explanation:   Let 'B' be the nuber of bricks.   =&gt; 10 x 4/100 x 5 x 90/100 = 25/100 x 15/100 x 8/100 x B   =&gt; 10 x 20 x 90 = 15 x 2 x B   =&gt; B = 6000   6000NSWER IS 6000
