To find 8x397, I used the stack method.
a.) 397
<u> x 8 </u>
3176
b.) This method works best because it's easy to do, and the factors aren't too big to multiply by hand, unless it was like a billion times a million. But in this case, it's not, so it's perfectly fine to use the stack method.
I hope this helps and have a good night! :D
My answer was 56/27. Here is the work I did.
Answer:
Step-by-step explanation:
The volume of a cube is 200 cm².
We need to find the edge length of the cube.
The formula for the volume of a cube is given by :
a is the side of the cube
![a=\sqrt[3]{200} \\\\=(200)^{\dfrac{1}{3}}\\\\=(25\times 8)^{\dfrac{1}{3}}\\\\=(25)^{\dfrac{1}{3}}\times (8)^{\dfrac{1}{3}}\\\\=2(25)^{\dfrac{1}{3}}](https://tex.z-dn.net/?f=a%3D%5Csqrt%5B3%5D%7B200%7D%20%5C%5C%5C%5C%3D%28200%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C%3D%2825%5Ctimes%208%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C%3D%2825%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5Ctimes%20%288%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5C%5C%3D2%2825%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D)
So, the edge length of the cube is .
