The volume of a pyramid is the one-third of the product of the area of the base and the height of the pyramid.
V = (1/3)Ah
where
A = area of base
h = height of the pyramid

The base of this pyramid is a hexagon.
The area of a regular hexagon is
A = (1/2)pa,
where
p = perimeter of the base
a = apothem

The perimeter of the hexagon is 6 * 6 ft = 36 ft.
The apothem is shown in the figure and is 5.2 ft.

Area of base: (1/2)pa = (1/2)(36 ft)(5.2 ft) = 93.6 ft^2

Volume = (1/3)Ah = (1/3)(93.6 ft^2)(8 ft)

Volume = 249.6 ft^3

Answer: 250 ft^3

What is 2/3 of the distance between the points U (-1,4) and B (8,5)
BlackZzzverrR [31]

Answer:

<h2>         6.037</h2>

Step-by-step explanation:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\U (-1,4)\quad\implies\quad x_1=-1\,,\ \ y_1=4 \\\\B (8,5)\quad\implies\quad x_2=8\,,\ \ y_2=5\\\\\frac12d=\frac23\sqrt{(8+1)^2+(5-4)^2}=\frac23\sqrt{81+1}=\frac23\sqrt{82}\approx6.037
