Step-by-step explanation:
Side of base of square, a = 10 km.
Height of pyramid , h = 12 km.
Volume of pyramid is given by :

Surface area is given by :

Therefore, volume and surface area are 400 km³ and 340 km² respectively.
Hence, this is the required solution.
Ok so differnce of 2 perfect ssquares are
x^2-y^2=(x-y)(x+y)
we are given
one factor is 5x-8
remember that all you do is square both terms individually to get them
(5x)^2=25x^2
8^2=64
they are difference so
25x^2-64 is answer
