  • Perimeter, generally denoted |P,| is the measure of the contour of a figure. To calculate the perimeter, we add the measures of all the sides. In the case of the circle, the perimeter is called circumference and is denoted |C.|

  • Area, generally denoted |A,| is the surface occupied by an object (in a 2 dimensional plane). Area is calculated in squared units (u2).

  • The area of the base, generally denoted |A_b,| is the surface occupied by the figure(s) that serve as base for the solids in question.

  • The lateral area, generally denoted |A_L,| is the surface occupied by the figures which do not serve as bases for the solids in question.

  • The total area, generally denoted |A_T,| is the total surface covered by all the figures forming the solids in question.

  • The volume, generally denoted |V,| is the portion of space occupied by a solid (in a 3 dimensional space). The volume is calculated in cubic units (u3).
