It is very much too bad that "A" doesn't exist and "B" is ambiguous. It is very difficult to solve when one cannot actually identfy the problem conditions.

Hello, mathe25!

Could explain the give quantities in words.
The letters need some explaining . . .

H of frustum pyramid is 7. . Is that the same as h ?
and A is 10 . What is A ?
and B is 2. . What is B? .Is that the area of the base?

i have to find side base.
Even if I knew what a "side base" is, I don't think I can find it.
[COLOR=#be0e]. . [/COLOR]There isn't enough information.

SECOND: side base make a angle from 45 . What does that mean?
and A is 6 . I still don't know where A is.
and B is 2. . And you've changed B to 2 ?

And what is the question?

Should we know what \(\displaystyle S\) and \(\displaystyle s\) represent?
. . Or should we ignore them?
