Correct answer

xxxxxxxxxx
 
width*height*length in "m^3"

The expected quantity.

Input hint

Allow unitless answer?

If not ticked, the student is prevented from submitting an answer without specifying units.

What to do if incompatible units used

If the student's answer is given in units incompatible with the correct answer's units:

"Prevent submission": Prevent the student from submitting until they use compatible units
"Mark as incorrect": Mark the student's answer as incorrect.
"Mark as if correct units used": Mark the student's answer as if they used the correct units, and apply the "different units used" penalty.

What to do if different units used

If the student's answer is given in different units to the expected answer:

"Convert" - silently convert the student's answer to the units used in the correct answer.
"Warn and convert" - show a warning to the student, but convert.
"Prevent submission" - don't allow the student to submit, and show a warning that they must use the same units.
"Mark incorrect" - the student's answer is marked as incorrect.

Penalty if different units used

100%

This penalty is applied if the student gives their answer in different units to the expected answer. The selected percentage of the student's score is taken away.

Margin of error

$10^{ -12 }$

The student's answer is marked correct if the difference between it and the correct answer is at most this value, measured in the same units as the correct answer.

Advice

a)

The volume of the parcel is given by

\begin{align}
\text{volume} &= \text{width} \times \text{height} \times \text{length} \\
&= \var{width} \times \var{height} \times \var{length} \\
&= \var{volume in "m^3"}
\end{align}
