We need to paint an auditorium, which is 24m long, 10m wide and 5m wide. After deducting the area of doors and windows of 64 square meters, if we need 5 yuan per square meter for painting, how much is it for painting the walls around the auditorium?

The total price of the paint used for the surrounding walls = (the area of the surrounding walls - the area of the doors and windows) * 5
If the auditorium is regarded as a cuboid paper box, the expanded view of the surrounding walls is a rectangle. The length of the rectangle is the perimeter of the ground, and the width is the height
So the area of the walls around is
[(24+10)*2]*3.5
=（34*2）*3.5
=68*3.5
=238 (M2)
The total amount is
（238-64）*5
=174*5
=870 yuan
