The volume, V, of a rectangular prism is determined using the formula, where / is the length, w is the width, and his the
height of the prism. Carltren solves for w and writes the equivalent equation w=
Using this formula, what is the width of a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches,
and a length of 3.2 inches?​

Answer:

[tex]\large\boxed{width=4.5\ in}[/tex]

Step-by-step explanation:

[tex]V=lwh\qquad\text{divide both sides by}\ lh\\\\\dfrac{V}{lh}=\dfrac{wlh}{lh}\\\\w=\dfrac{V}{lh}\\\\\text{We have}\\\\V=138.24\ in^3\\h=9.6\ in\\l=3.2\ in\\\\\text{Substitute:}\\\\w=\dfrac{138.24}{(3.2)(9.6)}=\dfrac{138.24}{30.72}=4.5\ in[/tex]
