A student measures the length of a rod XY by holding it next to a metre rule.
The student writes down the length as 94.8cm.
Which statement is correct?
The value is correct.
The value is incorrect because it should be 95.2cm.
The value is incorrect because it should be in millimetres.
The value is incorrect because the student should subtract the reading for end Y from the reading for end X.
