A student decides it is possible to estimate the capacity of a test tube by treating it as a rectangle and neglecting it's "roundness". On this basis, the student finds the capacity of the test tube to be 100.7 mL. In fact, the real capacity of the test tube is 100.0 mL. What percent error has resulted from the student's assumption?
0.7%
