Answer:
formula =
volume of brick- 25×10×7.5= 1875 cubic cm.
volume of wall in cm= 15×100×2.5×100×1.25×100= 46875000 cubic cm
hence brick required = volume of wall/volume of brick
n= 46875000/1875= 25000
hence brick required are 25000

Answer:
3600
Step-by-step explanation:
Volume of pile of bricks = 450*200*120(since 1m =100cm)
volume of each brick =30*10*10
No. of bricks = volume of pile of bricks / volume of each brick
=450*200*120/30*10*10
= 3600
Therefore , 3600 bricks are there in the pile
