Question

suggest me a working model on SURFACE area and VOLUME. and ALGEBRAIC identities.........

☆ hey friend!!! ☆

here is your answer ☞

(1)
your question is quite different because working modals are made on the topics in which certain things have to move .
( moving part can be anything for example electrons etc..)

Now in your case every thing is differnt,

Now lets think out of the box

Make a sphere which gets converted into 1/4 part of sguare
(As circle 1/4 part is called sector)

Which shows radius, so that you can calculate every thing related to radius

(2)
Learning about surface area and volume requires practice.
we have to not only know the formulas for calculating the areas of various 2-D shapes and the volumes of various 3-D shapes, but we also have to creatively put those formulas together to find total areas and volumes.

The more practice they have, the better we'll get.

hope it will help you
