Formula for frustrum are as follows:
Volume = 1/3 pie ( r1^2+r2^2+r3^2) height
CSA = pie (r1+ r2 )× slant height
TSA = CSA + pie ( r1^2+r2^2)
Solve the problem urself with the help of formulas
It is easy

I have formulas also
but slant height is not right me in answer
U r having radius and height
Slant height =root h^2 +( r1- r2)^2
Got it .....
