Compute the work against gravity required to build a diamond column?

Compute the work against gravity required to build a diamond column of height 8m and triangular base. The base is the right triangle with sides 2m and 5m. The density of diamond is 3500 kg/m^3.





Please explain! This is for test corrections.|||Find the volume: V = h*area = 8*2*5/2 m^3


(area of triangle = 2*5/2 m^2)


Find the weight: w = mg = V*density*g


Work = weight*h/2


Explanation: The h/2 term accounts for the fact that the center of mass of the column has been raised by that amount. The solution assumes that the column has a constant cross-sectional area, although that isn't stated.|||Thank-you.
