Answer:
Height of boxes = 6 feet
Step-by-step explanation:
Height of boxes = H₁ + H₂
Height of first box,
[tex]H_1=2\frac{1}{3}=\frac{2\times 3+1}{3}=\frac{7}{3}[/tex]
Height of second box,
[tex]H_2=3\frac{2}{3}=\frac{3\times 3+2}{3}=\frac{11}{3}[/tex]
Height of boxes = H₁ + H₂
[tex]=\frac{7}{3}+\frac{11}{3}=\frac{18}{3}=6\\[/tex]
Height of boxes = 6 feet
