Applications for Learning to Build Space. Presented in an attractive way with a 3-dimensional view and spatial calculation simulation. The material contains 6 spatial shapes, namely: cubes, blocks, prisms, pyramids, tubes, cones and balls. Each building space contains material that is quite complete:
- Definition and Properties of Building Spatial
- Surface Area Formula for Building Space
- Space Build Volume Formula
- Space Building Nets

In addition to the very complete material, there is arithmetic simulation to calculate the surface area of ​​a geometric shape, and calculate the volume area of ​​a geometric shape. The simulation shows quite detailed from the calculation process using the formula, to the results of the calculation.
