<em></em>
Answer:
Step-by-step explanation:
Given
--- length
Required
Determine the surface area
The surface area of a cube is calculated as follows:
Substitute 6 for L
<em>Hence, the surface area of the cube is </em>
<em></em>
Plug in f(t) = 0. We do this because f(t) represents the height and a height of 0 means you're at the ground.
f(t) =-5t^2 + 20t + 60
0 = -5t^2 + 20t + 60
-5t^2 + 20t + 60 = 0
Now solve for t using the quadratic formula
