The volume of pyramid shown above is 147.97units and the height is is 9.6 units find the length of one edge of the square base

The formula fro the volume of a pyramid with a square base is:

Volume = L * L * H / 3

L * L * 9.6 / 3 = 147.97

L * L = (3 * 147.97) / 9.6

L * L = 46.24

Let's take the square root of both sides.

L = sqrt (46.24) = 6.8

The length of one edge of the square base is 6.8 units.
