The shape of the boat only affects how much energy is needed to move it (overcome friction) when floating on water. The boat has to have a high-enough profile so that when it is placed in water, it will not take on water. The amount of water displaced by the boat counteracts the weight of the boat exactly. When a 200-pound person steps into the boat, the boat will sink to displace an extra amount of water, the weight of which equal to 200 lbs. That is assuming the boat has not sunk yet.

The shape of a boat with a hull that displaces water creates buoyancy. When the boat sits in water, the displaced water exerts an equal and opposite force on the boat, pushing it upwards. This buoyant force allows the boat to float on the water's surface.
To make plasticine float, you can shape it into a boat or raft-like structure with a concave base. By redistributing the weight and displacing enough water, the plasticine will float instead of sink.
Yes it does because depending on the materials of the boat and how much their mass is can change the buoyancy of the toy boat. Boat can be designed to have less volume in order for it to have less density and be able to float. So if the material's mass is alot if can make the boat sink. If the material's mass is not alot then it can help the boat float. If the shape is designed to have more volume than mass it will float. If not then it will sink.
The science is called "displacement". If the shape of the boat allows the amount of the boat in the water to be less weight than the water it displaces it will float. If the amount of the boat in the water weighs more than the water it displaces it will sink.
Increase its volume by adding more plasticine. Shape it into a hollow, buoyant structure like a boat or raft. Use a light material, like a small piece of foam, to help it float. Mold the plasticine into a ball shape, which can displace water and float. Create an air pocket within the plasticine to increase its buoyancy.
A boat floats in water due to the principle of buoyancy, where the weight of the water displaced by the boat is equal to the weight of the boat itself. To help a boat float, it needs a shape that displaces enough water to support its weight. The design of the boat, including its hull shape and materials used, all contribute to its ability to float effectively.
No gold is more dense than water so it sinks and in the gold rush in Cali they paned underwater
It would probably work if you molded it into the shape of a boat though I've never tried......
anything you want that can float. You can be creative.
A heavy lump of plasticine floats when in the shape of a boat because the boat shape displaces a greater volume of water than the lump alone. This creates a buoyant force that is sufficient to counteract the weight of the plasticine, allowing it to float.
Boats float due to the principle of buoyancy, which is the upward force exerted by water that opposes the weight of the boat. The shape and design of the boat help displace enough water to create buoyant force, allowing it to float.
