Explanation:

Solve the problem step by step.

First,

Base area: 6 * 2.5 = 15

Then,

The area of the two smallersides:

2.5 * 4 = 10

10 * 2 = 20

After that,

The area of the two larger sides:

6 * 4 = 24

24 * 2 = 48

After all of the calculations, you add all of the sums up:

15+20+48

Which equals 83.

The equation form for this problem would be:

(6*2.5) + 2(2.5*4) + 2(6*4) = 83

Hope this helps and it wasn't too confusing!
