It's a brick with lots of holes which will allow air to flow freely through a wall of a house or other building and help with ventilation, prevent damp etc.
Air is an insulator of heat and prevents outside heat from entering the house.
calcium silicate bricks
Bricks are typically made from clay or shale, which are natural materials that are molded and then fired in a kiln to create a hard, durable product. Some bricks may also be made from concrete or other composite materials. The specific composition can vary based on the type of brick and its intended use, such as standard bricks, fire bricks, or decorative bricks.
A course of brick is an entire horizontal row of bricks.
there are 500 bricks are counted for 1 m
Yes.
if you mean cubic metres bricks have a density of about 2.4 kg/ litre and air is about 1.2 kg/ m3 so 2.4 x 2 = 4.8 metric tons for bricks 1.2 x 6000 = 7.2 metric tons for air therefore air has more mass
-- The bricks and the feathers have the same weight.-- The bricks and the feathers have the same mass.-- The feathers have more volume than the bricks.-- The bricks have more density than the feathers.-- Neither the package of bricks nor the package of feathers is edible.-- The bricks definitely sink in water, whereas the feathers may float on water.-- When dropped through air, the feathers fall slower than the bricks, because of air resistance.-- I'm guessing that the feathers cost more than the bricks.
Air definitely has lower mass than bricks.
That only happens when they fall through air. The reason is the friction of the respective bodies plowing through the amount of air that each is in contact with. In the absence of air, bricks and cotton would accelerate at the same rate, reach the same speed at the same time, and hit bottom together.
Hollow bricks are used as air is a good insulator. Thick walls are used to reduce heat loss to the surroundings as the brick is also a poor conductor of heat. (although not as much effective as air)

The collective noun for bricks is a course of bricks.
Lego bricks are little blocks and Lego bricks can connect to other Lego bricks
I would guess that it is to make a better mortar joint. Mortar is forced into these holes and holds the bricks together better. Also the holes make the bricks lighter and air in the holes acts as insulation. I moved your question out of math to where I hope you will get a definitive answers.
Bricks are not flammable, but coal bricks are. IF THERE IS A BETTER ANSWER, IMPROVE.
Ofcourse,in my opinion in air because particles in air move fastest and move randomly and freely in all directions......Steel and bricks are solids....Solid paricles vibrate in a fixed position....Water is a liquid..Liquid particles slide upon each other
