find the total area of the prism.

144 sq. in.
576 sq. in.
864 sq. in.

864 sq.in.

Step-by-step explanation:

Given:

Prism with each leg of length 12

hence given prism is cube

Formula for Area of cubic prism= 6a^2

where a is length of a side

Area=6(12)^2

        =6(144)

         =864 !

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 %
