Having the length of a side(noticed with l), the volume of the cube is equal to:
V = l*l*l
V=l^3
To find the numeric value of l: l =![\sqrt[3]{V}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7BV%7D%20)
In our problem V = <span>256
l = </span>![\sqrt[3]{256} = \sqrt[3]{2^8} = 2^2\sqrt[3]{2^2} = 4 \sqrt[3]{4}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B256%7D%20%3D%20%20%5Csqrt%5B3%5D%7B2%5E8%7D%20%3D%20%202%5E2%5Csqrt%5B3%5D%7B2%5E2%7D%20%20%3D%204%20%5Csqrt%5B3%5D%7B4%7D)
V = l*l*l
V=l^3
To find the numeric value of l: l =
