WA.6.4. Core Content: Two- and three-dimensional figures (Geometry/Measurement, Algebra) Students extend what they know about area and perimeter to more complex two-dimensional figures, including circles. They find the surface area and volume of simple three-dimensional figures. As they learn about these important concepts, students can solve problems involving more complex figures than in earlier grades and use geometry to deal with a wider range of situations. These fundamental skills of geometry and measurement are increasingly called for in the workplace and they lead to a more formal study of geometry in high school.
6.4.E. Determine the surface area and volume of rectangular prisms using appropriate formulas and explain why the formulas work.
