    Question

    If the perimeter of a square is 56 cm and the side of the

    square is double of the side of the cube, then find the volume of the cube.
    A 343 cubic cm Correct Answer Incorrect Answer
    B 512 cubic cm Correct Answer Incorrect Answer
    C 216 cubic cm Correct Answer Incorrect Answer
    D 729 cubic cm Correct Answer Incorrect Answer

    Solution

    We know that, perimeter of the square = 4 X side

    So, 56 = 4 X side

    So, the side of the square = 14 cm

    So, the side of the cube = (14/2) = 7 cm

    We know that, volume of the cube = side 3

    So, the volume of the cube = 7 x 7 x 7 = 343 cm 3
