Volume of wall = ( 24 × 5 × 0.25 ) m^3 = 30m^3
Volume of 1 brick = (25/100 × 12.5/100 × 7.5/100) m^3 = 0.00234375
Volume of wall which is not covered by bricks = (5/100 × 30) m^3 = 1.5
Volume of wall which is covered by bricks
=(30-1.5)m^3 = 28.5 m^3
So number of bricks
= 28.5 / 0.00234375
= 12160
Hope that this will help you.
Brainlist it if it helps you.
