This guide explores fundamental 3D shapes, including rectangular solids, cubes, cylinders, cones, and pyramids. Each shape is defined along with distinguishing characteristics: a rectangular solid has six rectangular faces; a cube features six square faces; a cylinder consists of two congruent circular bases; a cone has a circular base leading to a single vertex; and a pyramid has a polygonal base with triangular faces converging at a vertex. Visual references and further resources are included for deeper understanding.
E N D
Rectangular Solid A rectangular solid is a 3D object with six sides, and each side is a rectangle.
Cube A cube is a 3D shape with six square faces
Cylinder A cylinder is a 3D figure with two parallel bases that are congruent circles. Parallel means the same distance apart. Congruent mean they are the same shape.
Cone A cone is a solid with a circular base and a vertex that is not in the same plane as the base A vertex is a point, so it is the top of the cone.
Pyramid A pyramid is a 3D figure whose base is a polygon and whose faces are triangles with a common vertex. A polygon is a figure with many sides.
