    Answer:

    Step-by-step explanation:

    1 . Sphere :

        Surface \ Area = 4\pi r^2\\\\ Volume = \frac{4}{3} \pi r^3

      Variable is ‘ r ‘

      Others Constants.

    2. Cone :

       Surface \ Area = \p r^2 + \pi rs          [ \ s = \sqrt { r^2 + h^2 } \ , r = base \ radius, h = height \ ]

        Volume = \frac{1}{3} \pi r^2 h

       Variables are ‘ r ‘ and ‘ h ‘

       Others constants.

    3. Cuboid ( Rectangular Prism )

       Surface \ Area = 2 ((l\times b) + ( b \times h) + ( l \times h)) \\\\Volume = l \times \ b \times \ h

       Variables : l , b , h

       Constant is 2

    4.  Cylinder

         Surface \ Area = 2 \pi r h + 2 \pi r^2 \\\\Volume = \pi r^2 h

        Variables : ‘ r  ‘ and ‘ h ‘

       Others constants..
