Answer:
16 square feet
Step-by-step explanation:
First, let's find how long each side of the cube is.
The volume of a cube is found by this formula, where s is a side of the cube:
![V = s^3](https://tex.z-dn.net/?f=V%20%3D%20s%5E3)
We can take the cube root of both sides:
![\sqrt[3]{V} = \sqrt[3]{s^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7BV%7D%20%20%3D%20%5Csqrt%5B3%5D%7Bs%5E3%7D)
Just flipping it:
![\sqrt[3]{s^3}=\sqrt[3]{V}\\s = \sqrt[3]{V}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bs%5E3%7D%3D%5Csqrt%5B3%5D%7BV%7D%5C%5Cs%20%3D%20%5Csqrt%5B3%5D%7BV%7D)
We know our volume is 64 cubic feet. Let's put that into our equation as V:
![s=\sqrt[3]{64}](https://tex.z-dn.net/?f=s%3D%5Csqrt%5B3%5D%7B64%7D)
The cubic root of 64 is 4, since 4 * 4 * 4 = 64
![s=4](https://tex.z-dn.net/?f=s%3D4)
Thus, each side of our cube is 4 feet.
Now, the area of a side of our cube is found using this formula:
![A = s^2](https://tex.z-dn.net/?f=A%20%3D%20s%5E2)
Since we know s, we can easily find the area A by squaring it:
![A = 4^2 = 16](https://tex.z-dn.net/?f=A%20%3D%204%5E2%20%3D%2016)
Answer: 16 square feet
Answer:
What is x pointing at? The Base or the Height?
Step-by-step explanation:
No.
I think they're trying to get you to recognize the associative property of addition, which states that (a+b)+c= a+(b+c)
So therefore (15+23)+7=15+(23+7).
Answer:
4
Step-by-step explanation:
13/3 = 4.33
4.33 rounds down to 4 or 4.30
Answer:
x = 56
Explanation:
You have a straight angle, and you’re given 2 angles. And since there are 3 angles that make up 180, we do:
180 - 64 - 60 = 56.
Hope it helps. ^^
