It floats because the shape of the hull with a large cavity inside displacing the water counteracts the weight of the metal hull. The water displacement counteracts the force of gravity, spreading the weight of the boat out across a larger surface area with a great tensile strength, resisting the force of gravity.
This is due to the principle of buoyancy, which is determined by the density of the object compared to the fluid it's in. A brick is more dense than water, so it sinks. However, a metal-hull ship is designed to displace enough water to create buoyant force greater than its weight, allowing it to float.
A brick weighs about 3.5 to 9lbs.
a brick
Half a pound.
it would be the brick because the brick has more matter because it weighs more.
Your typical brick used in construction, made of the commonest materials (baked clay, or mostly aluminum silicates) weighs about 4.5 pounds.
Weight will vary with size. An 8x4x2.25 inch brick weighs ABOUT 5 pounds.
If a brick weighs 1 lb, then half a brick would weigh 0.5 lb. Therefore, 1 and a half bricks would weigh 1 lb (for the full brick) + 0.5 lb (for the half brick) + 1 lb (for the additional brick) = 2.5 lbs.
One kilogram of brick weighs as much as one kilogram of feathers. (I do not know what a "chesse of feathers" is...)
A brick typically weighs around 1 kg.
A brick weighs one kilogramme plus half-a-brick. What is its weight?
it equals a half a lb.
