Instructions
You are painting a wall. The instructions on the paint can says that 1 can of paint can cover 5 square meters of wall. Given a random height and width of wall, calculate how many cans of paint you'll need to buy.

number of cans = (wall height x wall width) ÷ coverage per can.

e.g. Height = 2, Width = 4, Coverage = 5

number of cans = (2 \* 4) / 5
               = 1.6
But because you can't buy 0.6 of a can of paint, the result should be rounded up to 2 cans.

IMPORTANT: Notice the name of the function and parameters must match those on line 13 for the code to work.

Example Input
3
9
Example Output
You'll need 6 cans of paint.

import math

def paint_calc(height, width, cover):
    number_of_paint = (height * width)/cover  //페인트갯수 구하기   
    round_up_can = math.ceil(number_of_can)   //페인트갯수 반올림하기 
    print(f"You'll need {round_up_can} cans of paint.")
    



# Write your code above this line 👆
# Define a function called paint_calc() so the code below works.   

# 🚨 Don't change the code below 👇
test_h = int(input()) # Height of wall (m)
test_w = int(input()) # Width of wall (m)
coverage = 5
paint_calc(height=test_h, width=test_w, cover=coverage)
