Hello!

`\bf ANSWER`

The volume of the square pyramid is approximately
`\boxed{ \bf 19.19~km^3}`

____________________________________________________________

`\bf EXPLANATION`

V =
`a^(2)`
`(h)/(3)`

First, we must find the area of the square base.

A = l * w

A = 3.5 * 3.5

A = 12.25 km^2

The area of the base is 12.25 km^2. Now, multiply the base area by the perpendicular height. Then divide by 3.

V = (12.25 * 4.7) / 3

V = 19.1916666667

V ≈ 19.19 km^3
