Step-by-step explanation:
Triangles on the top have surface area 15*14/2 there are four of them so multiply by four to get 420.
The rectangular sections all have area 12*14 except for the base. There are four of these equal sections, so the combined area is 672.
Lastly, the base has area 14*14, which is 196.
Summing all of these we get 1288
