Given:
V = 19,200 feet³ volume of the sculpture
H = 36 feet height of the sculpture
a = ? side length of the square base
The formula for calculating the volume of a pyramid is:
V = B H / 3 ⇒ B = 3 V / H
B = 3 · 19,200 / 36 = 19,200 / 12 = 1,600
B = a²
a² = 1,600 ⇒ a = √1,600 = 40 feet
a = 40 feet

Answer:
y=0.5x
Step-by-step explanation:
y=mx+b
y2-y1/x2-x1
plug in the numbers and you'll have your answer
2L + 2W = perimeter
dividing both sides by 2
L + W = (perimeter / 2)
Length = (perimeter / 2) -Width
Width = (perimeter / 2) -Length
