Answer 1

Answer:

240 bricks

Step-by-step explanation:

Volume of the cubical brick = 43³

Length of the cuboidal room

= 4.5 m

= 4.5m x 100cm

= 450 cm

Breadth of the cuboidal room

= 2.7m

= 2.7 m x 100 cm

= 270 cm

Height of the cuboidal room

= 1.8 m

= 1.8 m x 100 cm

= 180 cm

Volume of the cuboidal room

= L x B x H

No. of bricks that can fit in the cuboidal room

= Volume of the cuboidal room ÷ Volume of the cubical brick

= 450 x 270 x 180/45 x 45 x 45

= 10 x 6 x 4

= 240 bricks
