8. A structural block comprising:
a first sidewall section extending from a front face of the structural block, the front face having four sides, to a rear face of the structural block, the rear face comprising a first edge and a second edge opposite to the first edge, a third edge connecting the first edge to the second edge and defining a first series of an alternating protrusion and recess, and a fourth edge opposite the third edge and connecting the first edge to the second edge and defining a second series of an alternating protrusion and recess, the first sidewall section disposed between a top surface of the structural block and a bottom surface of the structural block;
a second sidewall section extending from the front face of the structural block to the rear face of the structural block and disposed between the first sidewall section and one of the top surface of the structural block or the bottom surface of the structural block, wherein a portion of the second sidewall section is non-parallel with and angularly disposed relative to the first sidewall section; and
a perpendicular section extending between the first sidewall section and the second sidewall section, the first sidewall section, second sidewall section and perpendicular section form a portion of one of the protrusions, whereby one of the first sidewall section and second sidewall section is a surface that is perpendicular to the front face, the rear face, the top surface and the bottom surface.
9. The structural block of claim 8 further comprising a third sidewall section opposite from the first sidewall section.
10. The structural block of claim 8 further comprising a third sidewall section opposite from and nonparallel to the first sidewall section.
11. The structural block of claim 8 further comprising:
a third sidewall section opposite from the first sidewall section; and
a fourth sidewall section opposite from the second sidewall section.
12. The structural block of claim 8 further comprising:
a third sidewall section opposite from and nonparallel to the first sidewall section; and
a fourth sidewall section opposite from the second sidewall section.
13. The structural block of claim 8 further comprising:
a third sidewall section opposite from and nonparallel to the first sidewall section; and
a fourth sidewall section opposite from and nonparallel to the second sidewall section.
14. The structural block of claim 8 further comprising a lip section extending below the bottom surface.
15. A structural block comprising:
a first vertical sidewall section extending from a front surface of the structural block to a rear surface of the structural block and disposed between a top surface of the structural block and a bottom surface of the structural block, where the front surface is approximately parallel to the rear surface and has a different number of sides than the rear surface;
a second vertical sidewall section extending from the front surface of the structural block to the rear surface of the structural block and disposed between the first vertical sidewall section and one of the top surface of the structural block or the bottom surface of the structural block, wherein a portion of the second vertical sidewall section is non-parallel with and angularly disposed relative to a portion of the first vertical sidewall section;
a first horizontal section extending between the first vertical sidewall section and the second vertical sidewall section;
a third vertical sidewall section opposite from the first vertical sidewall section;
a fourth vertical sidewall section opposite from the second vertical sidewall section, wherein a portion of the third vertical sidewall section is non-parallel with and angularly disposed relative to a portion of the fourth vertical sidewall section, and the portion of the first vertical sidewall section is parallel to the portion of the fourth vertical sidewall section; and
a second horizontal section extending between the first vertical sidewall section and the second vertical sidewall section, the first vertical sidewall section, the second vertical sidewall section and the first horizontal section forming one of a first protrusion or a first recess, the third vertical sidewall section, the fourth vertical sidewall section and the second horizontal section forming the other of the first protrusion or the first recess, wherein the protrusion has a surface that is perpendicular to the top, bottom, front and rear surfaces.
