$\text {Volume = } \dfrac{5}{2x + 8} \times \dfrac{x+4}{4} \times \dfrac{12}{x}$

---------------------------------------------------
Take out (x + 4) as a common factor :
---------------------------------------------------
$\text {Volume = } \dfrac{5}{2(x + 4)} \times \dfrac{x+4}{4} \times \dfrac{12}{x}$

---------------------------------------------------
Cross out (x + 4) :
---------------------------------------------------
$\text {Volume = } \dfrac{5}{2} \times \dfrac{1}{4} \times \dfrac{12}{x}$

---------------------------------------------------
Rewrite 12 as 4 x 3 :
---------------------------------------------------
$\text {Volume = } \dfrac{5}{2} \times \dfrac{1}{4} \times \dfrac{4 \times 3}{x}$

---------------------------------------------------
Cross out 4 :
---------------------------------------------------
$\text {Volume = } \dfrac{5}{2} \times \dfrac{ 3}{x}$

---------------------------------------------------
Combine into single fraction:
---------------------------------------------------
$\text {Volume = } \dfrac{15}{2x}$
