A solid with three sides is a cylinder.
It wouldn't be a cube if the sides aren't equal in length. It would be called a rectangular prism.
a cube
a tetrahedron is a geometric solid that has 4 sides, all trianglular - it's like a pyramid with a triaglular base.
Plane shapes you draw on paper. Solid shapes can be picked up. Examples of plane shapes would be circle, square, triangle, etc. Examples of solid shapes would be a sphere, a cube, pyramid, and so on. ■
Depends on how much it weighs, if its hollow then maybe it would float. But doubting it would if its solid.
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.
it is hollow so it will float
float
sink
The answer is yes it can, let me explain. A solid ball of silly putty will sink in water, however if you flatten out the ball and turn up the edges to make a bowl shape it will float like a boat.
That depends on the relative densities of the solid and the liquid. If the solid is denser than the liquid, the solid will sink. If the liquid is denser, the solid will float.
a book
NO, a solid piece of brass is heavier than water so it will sink.
A solid with three sides is a cylinder.
The clay boat (like a steel ship) displaces its own weight in the water. So, as long as the sides of the clay boat (or steel ship) is above the water level, it will float. A solid piece of clay will (like a stone) sink immediately.
A solid float on water if the density is lower than the density of water.
