Question

The sum of area of six faces rectangular box is 376 cm sq. if the sum of the squares of length breadth and height is 200 cm sq, find the sum of lenght ,breath and height.

Answer 1

24cm sq

Step-by-step explanation:

let's say,the length is x,breadth is y,and height is z.

.. given:2(xy+yz+zx)=376

and (x^2+y^2+z^2)=200.

As we know,(x+y+z)^2 ={x^2+y^2+z^2+2(xy+yz+zx)},

so,

x+y+z=the root of (376+200)

which is root of 576>>>24.

hence, the length+breadth+height = 24cm.......
