Answer:

[tex]\frac{5}{7} ft[/tex]

Step-by-step explanation:

Really, really easy!

The formula of a rectangular prism is

Volume= (Area of the base) (height)

[tex]V=Ah[/tex]

We can find the height by dividing both sides of the equation by the Area of the base.

That is

[tex]V=Ah\\\\\frac{V}{A}=\frac{Ah}{A}  \\\\\frac{V}{A}= h\\\\\frac{\frac{10}{21} }{\frac{2}{3} }=\frac{5}{7}  =h\\[/tex]

So the height is 5/7 ft
