Cross-sections are one way that two-dimensional objects are connected to three-dimensional objects.

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

Practice your 3D visualization skills by rotating 2D shapes. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice finding the surface area of 3D objects. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Twenty-four problems covering a variety of solid figure topics: dimensions, volume, surface and base areas. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click...
