The base of a tetrahedron has 3 that are of equal length; essentially, it's made up of four equilateral triangles (hence the 'tetra'). A pyramid base has 4 sides of the same length. in fact, There are actually an infinite number of such 'pyramid-like' objects, with different numbers of sides on the base.
To be 3 dimensional the sides must also have height.
A cube is a three dimensional object with all sides of equal length. A rectangle is a two dimensional figure with two pairs of sides equal in length. Three dimensional is like a rubrics cube, something you can hold. A two dimensional figure is something you can not hold, a drawing is two dimensional.
A sphere is a round object. It has no sides. The object is 3-D. (Three Dimensional)
A box is a three dimensional object, and you have only stated one dimension. _________________________________________________________________ A box has all of the same length sides. The volume of the box is 27mm3.
No. A triangle can be a two-dimensional object whereas a pyramid must be three-dimensional (with sides that are sloped).

Need a clear definition. Sounds like you are describing a 'cube' - almost.
A sphere is a round object. It has no sides. The object is 3-D. (Three Dimensional)
A two-dimension shape with eight sides is an octagon. A three-dimensional object with eight sides is an octahedron.
A box is a three dimensional object, and you have only stated one dimension. _________________________________________________________________ A box has all of the same length sides. The volume of the box is 27mm3.
An isosceles triangle.
No. A triangle can be a two-dimensional object whereas a pyramid must be three-dimensional (with sides that are sloped).
I can see two possible answers to this question:There exists no three-dimensional object with only two sides.Picture a two-dimensional circle. Now put it in the third dimension and inflate the center of it a little bit. It would be like a coin, but the edges of both sides converge to a single edge. This may or may not count as a "three-dimensional object with two sides," depending on various possible definitions of the words in that phrase.
A two-dimensional shape with six sides is a hexagon. A three-dimensional object with six square faces is a hexahedron.
