Answer 2

Dimensions of the room = 5m × 5m × 5m.

(Since the room is a cube and all sides of a cube are equal.)

Dimensions of the brick = 10cm × 10cm × 20cm.

Therefore ,Number of bricks that can be kept in the room =

DIMENSIONS OF THE ROOM /DIMENSIONS OF THE BRICK

= 5m × 5m × 5m/10cm × 10cm × 20cm

= 5×100cm× 5×100cm × 5×100cm/10cm×10cm×20cm = 6250.
