heptagon
That is called a pyramid.
28 is not a perfect square. A perfect square is an integer that is the square of another integer. 9 is a perfect square; it equal to 3 squared, or 3 X 3. Often, such numbers are called simply square numbers. While 28 is not a perfect square, it is a square number in the sense that it has a square root. by definition, the square root of 28 times itself equals 28.
Well here's some: A four sided shape. A shape tht has sides that are all equal. Not a rectangle. A shape that has no curved sides. A two dementional shape. Not a polyhedron Can only have one form can't be a different size

Square feet is a 2-dementional state whereas gallon(s) are 3-dementional in quality. Impossible to answer question. barbrasydow@att.net
It's called a crystal lattice
to carry genetic material and maintain a 3 dementional shape
you don't. inches is a measure of length. cubic inches is a measure of volume. As told by by ID1245921910. To Confirm this, Inches by its self can be expressed as 2 Dementional where as Cubic Inces is more as a 3 Dementional expression.
one dementional array and two dementional array
It means that a shape has Length, Width and Height 2D ( 2 dimensional) shapes only have Lenght and Hieght
That depends on where the forces will be coming from. If both structures are subjected to forces in 3 dimensions, then the 3 dimensional structure will be less apt to fall over or something. If by strength you mean not compressing, then the 2 dimensional structure might be better theoretically, though you couldn't really build a 2 dimensional structure.
Having depth, width and height.
heptagon
surface area is the measure of a 3dementional and 2 dementional object
Numbers with 3 or 5 factors are called square numbers.
