Help me please

The surface area is:

276cm^2

Step-by-step explanation:

10x5=50x2=100

4x5=20x2=40

10x4=40x2=80

100+40+80=220

6x2=12x4=48

2x2=4x2=8

48+8=56

220+56=276

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
