    A.) 513 m3 B.) 514 m3
    C.) 512 m3 D.) 502 m3
    Answer: Option 'C'

    Cube Volume = a3

    a3 = 83 = 512 m3



  • The side of a cube is 15 m, find it's surface area?

    A.) 1350 m2 B.) 1250 m2
    C.) 1300 m2 D.) 1450 m2
    Answer: Option 'A'

    Surface area = 6 a2 sq. units

    6 a2 = 6 × 225 = 1350 m2

    A.) 526 m2 B.) 506 m2
    C.) 518 m2 D.) 516 m2
    Answer: Option 'D'

    Lateral surface = 4 a2

    4 × 122 = 4 × 144 => 516 m2



  • The lateral surface area of cube is 100 sq.units. find the volume of cube?

    A.) 122 m3 B.) 135 m3
    C.) 125 m3 D.) 120 m3
    Answer: Option 'C'

    Lateral surface = 4 a2 = 100 sq.units

    a2 = 25

    a = 5.

    Cube volume = a3 => 125 m3



  • The volume of cube is equal to the surface area of that cube. Then find the distance of side of the cube?

    A.) 6 m B.) 7 m
    C.) 8 m D.) 9 m
    Answer: Option 'A'

    Cube volume = a3 cubic units

    Surface area = 6 a2 sq.units

    a3 = 6 a2

    a = 6 m
