Hi
my question is
if we have a cube that is 20cm cubed
And 2 lenths representing 24 cm and 23 cm
We want to find x which is the width
how do we do that ?
Are you sure you've copied the question correctly? Using your figures, the width is about 1/3 of a centimeter, which doesn't make much sense.
I'm not sure , but the question is really how do we find a length if we have two lengths with the area
You multiply the three sides together to find the volume of a cube.

To find the width of the cube, called x, given the lengths of two edges (24 cm and 23 cm), you can use the formula for the volume of a cube and a bit of algebra.
1. Begin by understanding the formula for the volume of a cube: V = x³, where V represents the volume and x represents the length of any edge.
2. Given that the volume of the cube is 20 cm³, you can substitute this value into the equation: 20 cm³ = x³.
3. Now, it's time to solve for x. You can start by taking the cube root of both sides of the equation to isolate the variable: ∛20 cm³ = ∛(x³).
4. When you simplify the left side of the equation, you get: ∛20 cm³ = x.
5. Finally, calculate the cube root of 20 cm³. In this case, it is approximately 2.714 cm. Therefore, the width (x) of the cube is approximately 2.714 cm.
To summarize, to find the width (x) of a cube given the volume and two lengths, you use the formula V = x³ and solve for x by taking the cube root of the volume.
