<span>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.</span>
Answer:
2.16 s
Step-by-step explanation:
When it hits the ground, height h=0 hence
0=45-10t-5t^{2}
5t^{2}+10t-45=0
t^{2}+2t-9=0
Using quadratic formula
x=-1+\sqrt 10\\ x=-1-\sqrt 10
Since time can't be negative, -1+\sqrt 10
t=2.16 s
