The bases of the prism below are rectangles. If the prism's height measures 3 units and its volume is 198 units^3. solve for x

The volume of a rectangular prism is given by
V=L*W*H
where
V=198 units3
L=6 units
W=x units
H=3 units
substitute given values
198=(6)*(x)*(3)
solve for x
198=18x
x=198/18
