A cube had a volume of 1/512 cubic meter. What is the length of each side of the cube using the formula "volume=Length×Width×Hight." Please explain your thinking.​

Answer:

The length of each side of the cube is [tex]\frac{1}{8}\ m[/tex]

Step-by-step explanation:

we know that

The volume of a cube is equal to

[tex]V=LWH[/tex]

but remember that in a cube

Length, width and height have the same value

so

Let

b-----> the length side of the cube

[tex]L=W=H=b[/tex]

substitute in the formula

[tex]V=(b)(b)(b)=b^{3}[/tex]

In this problem we have

[tex]V=\frac{1}{512}\ m^{3}[/tex]

substitute and solve for b

[tex]b^{3}=\frac{1}{512}[/tex]

[tex]b=\sqrt[3]{\frac{1}{512}}\\ \\b=\frac{1}{8}\ m[/tex]

therefore

The length of each side of the cube is [tex]\frac{1}{8}\ m[/tex]
