    I learn in class 7B. It is a class with size about 20 metres square with white paint that covered all the walls. In my classroom there are about 14 tables and chairs for the students. They are arranged well. Each table is for two students. In front of tables and chairs, there are two sufficiently large whiteboards. Above the whiteboard, there is pair of photos of President and Vice President of Republic Indonesia and also Pancasila symbol. Besides the photos of president, there are also many heroes' pictures hanging on the wall.

    At the corner of my classroom, there is a cabinet used to store janitorial tools such as brooms, feather duster, and others. Right next to the cabinet, there is a teacher's desk which is covered with blue table cloth. On the teacher's desk, there is a beautiful flower vase and a pile of books that ordered well.

How many students are there in class 7B?
