Given parameters:

Length of the gift box = 8 inches

Width of the box = 3 inches

Height of the box = 4 inches

Unknown :

Length of its longest diagonal = ?

Solution:

This is a rectangular box.

To find the diagonal of such box, let us use the formula below;

             Diagonal  = \sqrt{l^{2} + w^{2} + h^{2}   }

l is the length

w is the width

h is the height

Input the parameters and solve;

           Diagonal  = \sqrt{8^{2} + 3^{2} + 4^{2}   }   = 9.4inches

The diagonal of the box is 9.4inches

Rolands suitcase has a mass of 2,500 dekagrams. How many kilograms is his suitcase?
Tasya [4]
A decagram is 10 grams, so first lets convert the decagrams to grams and then after we'll change to kilograms.
If 1 decagram equals 10 grams, then 2500 decagrams is equal to:
2500*10 = 25000 grams
Now, 1 kilogram equals 1000 grams so 25000 grams equals:
25000/1000 = 25 kg
therefore, 2500 decagrams equals 25 kg
