SURFACE AREA OF A CUBE

Hello! Are you ready to carry out learning activities at this meeting? In this meeting we will learn about "Surface Area of a Cube". Students are allowed to open a book of teaching materials as a reference source.
Indicators of Competence Achievement :
  • Understanding the surface area of a cube
Working Instruction :
  • Pray before studying.
  • Form groups with 3-4 students in each group.
  • Discuss the answers to the problems with a group of friends.
  • Ask the teacher if you have difficulty.
  • Present the results of your discussion in front of the class in each section.
Note: In this activity there is no send button, students simply answer the question in the answer column provided and the answer will be automatically recorded.
