8*.8=6.4
4x+6.4=40
40-6.4=33.6
33.6/4=x
8.4=x
Hope this helps :)

Answer:
288 km²
Step-by-step explanation:
The surface area is the sum of the area of the square base and the area of the four triangular faces.
SA = (10 km)² + 4(1/2)(10 km)(9.4 km) = 288 km²
____
The area formulas for a square and a triangle are ...
A = s² . . . . area of a square of edge length s
A = 1/2bh . . . . area of a triangle with base b and height h
So you will have to find the difference between each number so 6--2=8
and 8--2=10. So then I'm guessing you have to round 8 to 10. Sorry if this isn't all correct.
