Question

how many bricks will be required for a wall which is 1 metre long ,6 metre high and 22.5 CM thick.If each breaks measures 25 cm× 11.25 cm × 100 cm

Answer 1

$\frac{ 100 \times 600 \times 22.5}{25 \times 11.25 \times 100}$
convert metre into cm amd divide the volume of both ( the volume of brick by that of wall )

Answer 2

HEY!MATE HERE IS YOUR ANSWER I CAN HOPE YOU UNDERSTAND...

FIRST,FIND THE VOLUME OF WALL AND THEN DIVIDE IT BY VOLUME OF BRICKS...

SO,25×11.25×100÷100×600×22.5​ 
25×1125×100×10÷100×600×225×100
25×1125÷600×225×10
28125÷1350000
vol.of bricks÷vol. of wall
vol.of wall ÷ vol. of bricks
1350000÷28125
48...

The no. of bricks needed is 48...
