It is true.

Each side of the cube is 8 units, so the perimeter of one side is 4*8 = 32.
To find the percent of 15 out of 60, you have to divide fifteen by sixty.
Then, you multiply your answer by 100. (We do this because 100 percent is a exact amount. 100% of sixty is...well, sixty.)
15 / 60 = 0.25
Now, we can multiply 0.25 by 100:
0.25 * 100 = 25 (basically just moving the decimal two places to the right.)
Next, add a percent sign:
25%, is your answer.
15 is 25% of 60.
