Finding length and with of a rectangular prisum given limited info.

Question

I need to find length of a rectangular prisum. I am only given the following info.

Volume = 2,400 Cu Ft,

Height = 12 ft,

l= With(w)*2.

 

thank you! 

 

Answer 1

Rectangular Prism:     "A solid (3-dimensional) object which has six faces that are rectangles."

 

The common name is "BOX."

 

The volume of a rectangular prism = length * width * heighth

                                                    (width*2) * width * 12 = 2400

                                                          width*24 = 2400

                                                           width - 10 ft

 

     And,   length = 2 * width         [that's easy to compute]

 

Now, just to check, is length*width*height = 2400   ???
