Question

how many bricks each 25 CM by 15 CM by 8 cm required for a ward 35 long 3 metre high and 40 cm thick​

Answer 1

Answer:

3500×300×40÷25×15×8

Answer 2

Answer:

length of ward= 35m =35m × 100 =3500cm

width of ward= 40cm

height of ward = 3m = 3m ×100 = 300 cm

so,

Volume of ward= L × B × H

= 3500 × 40 × 300

= 3500 × 12000

= 42000000 cm^3

Now,

Length of brick= 25cm

width of brick= 15cm

height of brick = 8cm

SO,

Volume of Brick= L× B × H

= 25 × 15 × 8

= 25 × 120

= 3000 cm^3

No. of Bricks = Volume of Ward
