You find the area of each of its faces and add them together.
Obviously, the area of each face will depend on its shape.
A 2D shape is flat and only has a surface area whereas a 3D shape is an object that has surface area and volume.
That will depend on what they are but in general 3D shapes have surface area and volume whereas 2D shapes have only surface area.
It is the total surface area of the shape.
A cube is a 3D shape that has 6 faces of equal area.
least volume and most surface area is 3D triangle
It depends on the 3d shape.
It is not a 3D shape.
A camera is a 3D shape. A photograph is a 2D projection of a 3D shape onto a 2D shape.
Well it depends on what kind of 3d shape it is. There is a formula to find the volume of each 3d shape. The main formula for volume is Bxh. (Big B multiplied by the height.) Bxh means the area of the base times the height.
a pyramid is a 3D shape :)
what 3d shape is a tyre
is a square a 3d shape
