I'll mark the best or first as brainlest.

6 * 2.5 = 15 That’s the area of the base

2.5 * 4 = 10
10 * 2 = 20
That’s the area of the 2 smaller sides

6 * 4 = 24
24 * 2 = 48
That’s the area of the 2 larger sides

Then you add all the dimensions together.

15+20+48 = 83.

So, the final equation is (6*2.5) + 2(2.5*4) + 2(6*4) = 83
Mark me brainliest please

The answer will be 83

The answer is 8 apex

The correct awnser is 29.76 pounds.
