the answer is 50.24 cm²
hope this helps.
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
.
Answer:
3:4
Step-by-step explanation:
Hello,
Shall we begin?
= 2 + 2×9÷3+10-45+21
= 2 + 18 : 3 + 10 - 45 + 21
= 2 + 6 + 10 - 45 + 21
= - 6
