In the oblique triangular prism below, CH = (x + 1) cm, EG = x cm, A F = x + 3, and AC = 4x cm.
A triangular prism is shown. The bases are triangle A B C and triangle F E D. A bisector is drawn from point E to point G on side F D. Line F D is extended to point H outside of the figure. Another line is drawn from point C to point H to form a right angle. The length of C H is (x + 1) centimeters, the length of E G is x centimeters, the length of A F is x + 3 centimeters, and A C is 4 x centimeters.

Which statements are true regarding the prism? Check all that apply.

CH is the height of the prism.
The area of the base of the prism is One-half(4x)(x).
The formula for finding the volume of the prism does not include A F.
The formula for finding the volume of the prism can be represented by the expression 4x3 + 4x2.
The lateral faces of the prism are congruent.
