Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
While driving up a road, Philip passed through 5 intersections. 4 crosswalks marked each intersection with a total of 20 lines per crosswalk. Calculate the total number of lines of the crosswalks in the five intersections.

### Response:
If one intersection has 20 lines per crosswalk in all the 4 crosswalks, the total number of lines in one intersection is 20*4 = <<20*4=80>>80
If there are 5 intersections, the total number of lines in all the intersections is 80*5 = <<80*5=400>>400
#### 400
