    Question

    A cube has a surface area of 294 m². What is the length (in cm) of the side of the cube?

    A.

    0.7 m

    B.

    700 cm

    C.

    0.7 cm

    D.

    700 m

    Correct option is B

    Given:
    Surface Area (S) = 294 m2
    Formula Used:
    Surface Area of a Cube = 6 × (Side)2
    Where, Side = length of one edge of the cube
    Solution:
    294 = 6 × (Side)2
    => (Side)2 = 294 ÷ 6
    => (Side)2 = 49
    => Side = √49
    => Side = 7 m
    => Side in cm = 7 × 100
    => Side = 700 cm
