Help plz thank you I appreciate if u guys can help me

step-by-step explanation: as sides and hieghts are not mentioned so

i assumed myself that

one base side = 11

second base side = 15

third base side= 16

height= 17

surface area = (surface area of lower base) + (surface area of uper base)+{( one base side +second base side + third base side)}×height

                  =     872
