Answer: 12
Step-by-step explanation:
One yard is three feet. So three times four is 12 because it makes four yards in total with each side being a yard.
Answer:
80
Step-by-step explanation:
89^2-39^2=6400, 6400=80^2
V=1/2a*c*h this is to solve the volume of a prism
The volume of a pyramid is V = 1/3 x base length^2 x height
Let X = base length.
We are told the height is 1/2 the length, so height would be 1/2x
Now we have:
972 = 1/3 * x^2 * 1/2x
Simplifying we get:
972 = 1/6x^3
Multiply both sides by 6:
5832 = x^3
Take the cube root of both sides:
x = 18
The length of the base is 18 inches.
The height is 1/2 that, so the height would be 18/2 = 9 inches.
