Question

A brick measures 20×10×3.5cm.How many bricks will be required for a wall of dimensions 25×2×0.35.

Answer 1

STEP BY STEP EXPLANATION

TO find how many bricks required formula will be $\frac{Volume\:of\:wall}{volume\:of\:bricks}$

SO ACCORDING TO QUESTION::
VOLUME OF 1 BRICK =20×10×3.5
= 700cm
VOLUME OF WALL = 25×2×0.35m
17.5
SO, NUMBER OF BRICKS REQUIRED = $\frac{Volum\:of\:wall}{volume\:of\:1\:brick}$

=$\frac{2500×200×35}{20×10×3.5}$

= 250×10×10
= 25000
25000 bricks are required to build the wall
