Answer:
6.724 cm to nearest thousandth.
Step-by-step explanation:
I am assuming it is x cubed as we are talking about the volume.
Let the width be x cm, then the length is 2x and the height = 3x cm.
So we have the equation:
x * 2x * 3x = 228 (because volume = length*width*height).
6x^3 = 228
x^3 = 38
x = ∛38
= 3.362
So the length = 2 * 3.362
= 6.724 cm to nearest thousandth.
