Question

If the ratio of length breadth and height of a cuboidal box is 3:2:1 and it's volume is 384cm.then let us calculate the total surface area of the box.

Answer 1

let the height of cuboid be x
than length =3x
breadth=2x
since volume of cuboid =length *breadth*height
therefore
X*2X*3X=384
6x^3=384
x^3=64
X=4
now total surface area of cuboid =2(length*breadth+breadth*height+height*length)
now put the value of X in above eqn to find out length breadth and height
and backput these values in above formula of tsa you will get Ur answer
