I will be student teaching in the fall. I will be teaching 8th grade Algebra. I have been reviewing over the book because I took my college algebra class 10 years ago. My question is why at the beginning of the book the volume of a right prism is taught perimeter(lateral surface area) times height and later in the book volume of a prism is taught area of base times the perpendicular distance between the bases? Is there a good reason for the different formulas? Also do both formulas render the same solution?
