We know that
[volume of a square pyramid]=area of the base*height /3
area of the base=3*volume/height
volume=245 in³
height=15 in
area of the base=3*245/15-------> 49 in²
the area of the base is a square
so
area=b²---------> b=√area---------> b=√49-------> b=7 in
the answer is
T<span>he length of one side is 7 in</span>

Answer:
3.81 s
Step-by-step explanation:
Let's consider the following formula that represents the journey of a falling object.
d = 3 t + 5 t²
where,
- d is the distance measured in feet
- t is the time measured in seconds
We can find the time that it will take to travel 84 feet by replacing d = 84 in the equation.
84 = 3 t + 5 t²
5 t² + 3 t - 84 = 0
We have a = 5, b = 3 and c = -84. We apply the second grade solving formula.
x₁ = 3.81 and x₂ = -4.41
Since the time cannot be negative, the answer is t = 3.81 s
