[tex]\text { Volume = } 4\dfrac{1}{4} \times 5 \times 2[/tex]

--------------------------------------------------
Change to improper fractions :
--------------------------------------------------
[tex]\text { Volume = } \dfrac{17}{4} \times \dfrac{5}{1} \times \dfrac{2}{1} [/tex]

--------------------------------------------------
Combine into single fraction :
--------------------------------------------------
[tex]\text { Volume = } \dfrac{170}{4} [/tex]

 --------------------------------------------------
Simplify:
--------------------------------------------------
[tex]\text { Volume = } 42 \dfrac{1}{2} \ cm^3[/tex]
