The maximum height of the projectile is the maximum point that can be gotten from the projectile equation
The projectile reaches the maximum height after 5 seconds
The function is given as:

Differentiate the function with respect to t

Set to 0

So, we have:

Collect like terms


Solve for t


Hence, the projectile reaches the maximum after 5 seconds

V ≈ 15.63cm^3
volume of a cube = side × side × side = units^3
Volume = 2.5*2.5*2.5 = 15.63^3
