width of the rectangular prism is 4.5 inches.
Carltren solves for w and writes the equivalent equation as
Now, we have to find 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.
Thus, we have
V = 138.24 cubic inches
l = 3.2 inches
h = 9.6 inches.
Substituting these values in the above formula to find w
On simplifying, we get
Thus, width of the rectangular prism is 4.5 inches.
