The base area of the original prism is 6ft^2. If it is dilated by a scale factor of 3/2, then the base area of the dilated prism would be
6 x 3/2 = 9 ft^2
If the original height is 7ft, then the height of the dilated prism would be
3/2 x 7 = 10.5
The formula for determining the volume of a prism is
Volume = base area x height
Volume of dilated prism = 9 x 10.5 = 94.5 cubic feet
