We know that his woodshed is a parallelepiped, and 8' is the depth, 16' is the lenght and 6' is the height.
A cord of wood is 4' high, 4' deep and 96" long.
96" = 8'
We find the volume of his woodshield.
V = h*d*l = 168*6 = 768 cubic feet
Find the volume of a cord
4*4*8 = 128 cubic feet
Do the ratio: 768/128 = 6
His woodshield can hold 6 cords.
For the second question, simply do a multiplication.
If 1 cord is $120, how much are 6?
120*6 = $720
The answer is <span>A. 754 ft^2

The area (A) of a cone with radius r and height h is:
A = π r² + π r√(h² + r²)
We have the slant height l, so we will calculate h using the formula:
l² = r² + h²
h² = l² - r²
So:
l = 14
d = 20 - diameter
r = d/2 = 20/2 = 10
h = ?
h² = l² - r²
A = π r² + π r√(h² + r²)
A = π r² + π r√(l² - r² + r²)
A = π r² + π r√l²
A = π r² + π r l
A = 3.14 * 10² + 3.14 * 10 * 14 = 3.14 * 100 + 439.6 = 314 + 439.6 = 753.6 ≈ 754

Answer:
m = 123, g = 273
Step-by-step explanation:
m is the number of monkeys, g is the number of giraffes. We will use a system of equations.
m + g = 396
g = 2m + 27
Plug g into the first equation.
m + 2m + 27 = 396
Add like terms.
3m + 27 = 396
Simplify.
m = 123
Plug the value of m into the second equation
g = 2(123) + 27
Simplify
g = 273
