Key Points
- To find the side length of the cube, we need to use the formula for the volume of a cube, which is V = a³, where "a" is the side length.
- Given that the volume of the cube is 64 mL, we set up the equation: a³ = 64.
- Taking the cube root of both sides, we find that a = 4 cm. This is because (4 cm)³ = 64 cm³.
- Since 1 mL of water is equal to 1 cm³ in volume, the units are consistent, and the side length is correctly calculated in centimeters (cm).
- A cube with side length 4 cm has a volume of exactly 64 cm³, which matches the given volume of water.
- Thus, the correct answer is 4 cm.
