Answer:
i got 306 as the answer
Step-by-step explanation:
find the surface area of the cuboid alone;
12 by 4 by 2 because there is a similar face in the opposite side. = 96
5 by 4 by 2 = 40
12 by 5 by 2 = 120
then you find the surface area for the pyramid on top ;
1/2 by 5 by 5 by the 4 faces = 50
the base was gotten by subtracting 7 from 12
