Step-by-step explanation:
Q.
A brick had dimensions 15 cm × 8 cm × 5 cm. Find the number of bricks in a chamber of volume 216 m³.
Solution -
First of all, we have to find the volume of brick
Volume of cuboid = l × b × h
Volume of brick = 15 cm × 8 cm × 5 cm
= 600 cm³
Now,
1 m³ = 100000 cm³
216 m³ = 216000000 cm³
Number of brick in chamber = Volume of chamber / volume of brick
= 216000000/600
= 2160000/6
= 360000 bricks
So there are 360000 bricks in the chamber.
hope it helps.
