Question

calculate the surface area of a cube and volume of a cube with the given diagonal length of 15square root of 3cm

  1. 3375, 1390
  2. 4320,3470 
  3. 1350, 3375
  4. 1570, 3695

Hint:

 Total Surface Area(TSA) of cube = 6a2
Volume of a cube = a3
where,   a is side of cube

The correct answer is: 1350, 3375


    We have given the diagonal of the cube
    D= 15square root of 3 cm
    We have to find the Surface area and volume of the cube.
    We know that Diagonal of the cube = square root of 3a
    Where a is side of the cube
    Comparing with the given value we get

    a = 15 cm
    Therefore , Surface area of cube = 6a2

    = 6(15)2

    = 6(225)

    = 1350
    And, volume of the given cube = a3

    = (15)3

    = 3375
    Therefore the correct option is c)1350, 3375.
