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
volume of wall in cm= 15×100×2.5×100×1.25×100= 46875000 cubic cm

Step-by-step explanation:
Volume of brick = 25 cm × 10 cm ×7.5 cm = 1875cm³ Volume of the wall in cm³ = 15 × 100 × 2.5× 100 × 1.25 × 100 = 46875000cm³. Number of bricks = 46875000/1875 = 25 000 bricks
