The length breadth and height of two boxes are 3,4,6 and 3,5,h but their diagonal are equal find h.
Answers
Considering the first box. The dimensions i.e. length, width and height are 3, 4 and 6. I am giving notation for root as R and square as S. While taking note of this problem replace R with root symbol and S with square symbol.
The length of base diagonal is R(3S+4S) = R(9+16) = R(25) = 5
Now calculating the major (Box i.e. in Cuboid shape) diagonal, the two sides (of right angled triangle) will be height (6) and base diagonal (5). It is R(5S+6S) = R(25+36) = R(61).
Going to second Boxthe diomensions i.e. lenght, breadth and height are 3,5 and h.
The length of base diagonal is R(3S+5S) = R(9+25) = R(34)
For calculating the Box (major) diagonal, the two sides (of right angled triangle) will be height h and base diagonal (R(34)). It is R(hS+R(34)S). But this is equal to R(61).
R(hS+R(34)S) = R(61).
Squaring on both sides hS+34=61.
h = R(61-34)
h=R27
h=3R3
So the height of second box is 3root3.
