Answer:
The answer is 792.
Step-by-step explanation:
I got the answer by first imagining how the 3d shape looks ike. Since one of the sqaure base length is 11 I found the base surface area by doing 11 times 11.My answer was 132. The since one of the slant length of the pyramid's triangle is 15, I did 11 times 15, my answer was 165. There are four triangles in the pyramid so I did 165 times 4, my answer was 660.
All the triangle surface area is 660 plus the sqaure surface are which is 132, that gave me my answer 792.
I am pretty sure it is talking about interest and $640 is what you start with, with a 3% interest for 2 years
