title: Calculate total litres required to fill carpark using python3
body: <p>I have to work out how many liters of concrete can fit into a park. Len park: 30.2m | wid of the park: 10m | liters per sq/m: 6.6. I have attempted this and am new to python and know how to calculate the total. (30.2 * 10 * 6.6 = total). But I'm struggling to print the result.</p>
  <pre class="lang-py prettyprint-override"><code>length = 30.2
  
  width = 10
  
  squared = 6.6
  
  length = int(input('Length of park (m):'))
  
  width = int(input('Width of park (m):'))
  
  squared = int(input('Litres per square metre:'))
  
  sum = length * width * squared # calculate total metres to get answer
  
  print(&quot;Litres Required =&quot;,sum)
  
  # print total amount of liters required 
  </code></pre>
