Answer
The total weight of the ground material is $~~1.4\times 10^9~N$
Work Step by Step
We can find the total weight of the ground material:
$W = mg$
$W = \rho~V~g$
$W = (2800~kg/m^3)(150~m)(60~m)(5.8~m)(9.8~m/s^2)$
$W = 1.4\times 10^9~N$
The total weight of the ground material is $~~1.4\times 10^9~N$
