Question

A brick has a cubic shape and has an edges of length 45cm. How many such bricks can fit in a room having a length of 4.5 m, breadth of 2.7m and heightof 1.8m

Answer 1

HERE THE VOLUME OF THE TOTAL BRICKS WILL BE EQUAL TO THE VOLUME OF THE ROOM.

SO VOLUME OF ONE BRICK(CUBE)

=0.45^3m

=0.091125 m=0.09m^3

LET THE NUMBERS OF BRICKS BE X

SO X ×0.09m^3=VOLUME OF THE ROOM

X=4.5×2.7×1.8/0.091125

X=240

SO 240 BRICKS ARE NEEDED

Answer 2

Answer:

240 bricks

Step-by-step explanation:
