Answer:
B. 150 ft³
Step-by-step explanation:
The general formula for the volume of a pyramid is:
V = 
where B = the area of the base and h = height of the pyramid
Since the base of the pyramid is a square, we can take the length of the side squared:
A = s²
A = 5² = 25 ft²
Using B = 25 and h = 18:
V =

Answer:
y = 16.3
Step-by-step explanation:
We would apply the formula for altitude of a right triangle which is given as:
h = √(xy)
Where,
h = 14
x = 12
y = y = ?
Plug in the values
14 = √(12*y)
14² = (√(12*y) (squaring both sides)
196 = 12*y
196/12 = 12y/12 (division property of equality)
16.3 = y (nearest tenth)
y = 16.3
