Earth-boring tools having shaped cutting elements

A fixed-cutter bit, comprising:

• a fixed-cutter bit body having a plurality of blades;
• and
• at least one cutting element attached to a blade of the fixed-cutter bit body, the at least one cutting element comprising:
• a volume of superabrasive material, comprising:
• a cutting surface comprising a first side chamfer surface and a second side chamfer surface;
• a lateral side surface intersecting each of the first side chamfer surface and the second side chamfer surface;
• and
• a cutting edge at an intersection of the cutting surface and the lateral side surface;
• a base surface;
• and
• a longitudinal axis extending through the cutting surface and the base surface, wherein the longitudinal axis is perpendicular to the base surface;
• wherein the at least one cutting element is oriented to position a portion of the cutting edge most distal from the base surface in contact with an exposed surface of a subterranean formation when the fixed-cutter bit body is rotated within a wellbore.
