**ABSTRAK**

This research done caused low mathematics studentsâ€™ achievement. Particularly, many students have difficulty in solving Three Dimensional question. The aim at this research was describe kinds of studentsâ€™ error at class X.1 SMAN 3 Lubulinggau in solving Three Dimensional questions and the caused factors. The type at this research was descriptive research with the subject students of class X.1 SMAN 3 Lubuklinggau in academics years 2015/2016. The data collected through observation and interview. Based on the result from analyzing the data, it was conclude that kinds of studentsâ€™ error class X.1 SMA NEGERI 3 Lubuklinggau in solving Three Dimensional questions were: 1) Error facts 63,75%, 2). Error concept 56, 75%, 3). Error operation 61.75%, and 4). Error Principe 71.5%. The cause factors were: 1) The student forgot and lacks accuracy in writing the answers, completes the answers, calculation operations, and the student forgot to determine the rules of cosine; 2) Students did not understand the concept to solve the questions of the three dimensions and the students perform calculations based on reasoning rather than on the concept; 3) Students have difficulty in illustrating / abstracting images from geometry conditions which asked so the students took wrong conclusions; And 4) Students did not understand the triangle in the cube or limas space so the students wrong in stating the Pythagoras theorem.
