What is the side length of a cube with a volume of 27 mm³?
Taking the cube root:
- \( \sqrt[3]{27} = 3 \) because \( 3^{3} = 3 \times 3 \times 3 = 27 \) Cube: 3 mm, 3 mm, 3 mm V = \( 3^{3} = 3 \times 3 \times 3 = 27 \) Correct method.
Dividing:
- \( \sqrt[3]{27} = 9 \) because \( 27 \div 3 = 9 \) 9 mm, 9 mm, 9 mm
V = \( 9^{3} = 9 \times 9 \times 9 = 729 \) So this method of dividing is incorrect.
