if there are more than half boys then girls it as t be und .5 since that's half and .018 is to low
 
        
             
        
        
        
The formula is 1/3*height*area of base.
        
             
        
        
        
A quadrilateral is any figure with 4 sides, no matter what the lengths of 
the sides or the sizes of the angles are ... just as long as it has four straight 
sides that meet and close it up.
Once you start imposing some special requirements on the lengths of 
the sides,  or their relationship to each other, or the size of the angles, 
you start making special kinds of quadrilaterals, that have special names.
The simplest requirement of all is that there must be one pair of sides that 
are parallel to each other.  That makes a quadrilateral called a 'trapezoid'.
That's why a quadrilateral is not always a trapezoid.
Here are some other, more strict requirements, that make other special
quadrilaterals:
-- Two pairs of parallel sides . . . . 'parallelogram'
-- Two pairs of parallel sides 
AND all angles the same size . . . . 'rectangle'
           (also a special kind of parallelogram)
-- Two pairs of parallel sides 
AND all sides the same length . . . 'rhombus'
           (also a special kind of parallelogram)
-- Two pairs of parallel sides 
AND all sides the same length 
AND all angles the same size . . . . 'square'.
           (also a special kind of parallelogram, rectangle, and rhombus)
