Volume of a rectangular prism:


V=\text{Length}* Width* Height

Given prism:


V=(2)/(3)mm*(2)/(3)\text{mm}*1(3)/(4)mm

To multiply first write the mixed number as a improper fraction:


1(3)/(4)=1+(3)/(4)=(4+3)/(4)=(7)/(4)

The volume is:


\begin{gathered} V=(2)/(3)mm*(2)/(3)\text{mm}*(7)/(4)mm \\ \\ V=(2*2*7)/(3*3*4)mm^3 \\ \\ V=(28)/(36)mm^3 \\ \\ V=(7)/(9)mm^3 \end{gathered}

Then, the volume is 7/9 cubic milimeters
