Vocab/Object

Objectives

  • Identify surface area of prisms as the sum of the areas of faces using nets.
  • Find surface area of rectangular and triangular prisms using formulas.
  • Identify volumes of prisms as the sum of volumes of layers of unit cubes.
  • Find volumes of rectangular and triangular prisms using formulas.

Vocabulary

Surface area
the outer covering of a solid figure-calculated by adding up the sum of the areas of all of the faces and bases of a prism.
Net
diagram that shows a “flattened” version of a solid. Each face and base is shown with all of its dimensions in a net. A net can also serve as a pattern to build a three-dimensional solid.
Triangular Prism
a solid which has two congruent parallel triangular bases and faces that are rectangles.
Rectangular Prism
a solid which has rectangles for bases and faces.
Volume
the amount of space inside a solid figure
