You should start by calculating the area of one of the faces of the chosen figure. Then proceed by doing the same thing till you've calculated the area of all the surfaces. Then all you have to do is add them up.

Alex
Hello!

1 minute 3 seconds = 63 seconds

We must found out 63 is 90% of what number, using the percentage formula:

90 * 100 / 63 = 70

70 seconds = 1 minute 10 seconds

So, Niki's time for one lap is 1 minute 10 seconds (70 seconds).
