Question

Which is the side length of a cube with a volume of 512 cm3?        A. 3√512 cm       B. √512 cm    C. 512² cm      D. 512³ cm

2 Answer

  • The answer would be 512 to the power of 2 cm
  • Hi, apply the formula

    Vcube = Side power 2

    Vcube = Side^2

    As Vcube = 512cm^3

    Then,

    Side^2 = 512

    Applying square roots on both the side of equation:

    √(Side^2) = √(512)

    Canceling the square root with power 2

    Side = √(512) cm


    Then the answer to this question is option B)
