To find the length of one side of a wooden cube given its volume, you can use the formula for the volume of a cube:
V = s 3
where V is the volume and s is the side length of the cube. Given that the volume V is 0.4789 cm³, you can find s by taking the cube root of the volume:
s = 3 0.4789
To calculate 3 0.4789 , you can either use a calculator or apply estimation methods. Using a calculator, you can determine:
s ≈ 0.7824
Therefore, the length of one side of the cube is approximately 0.7824 cm to four decimal places.
The correct multiple-choice option is C. 0.7824 .
