M = (1/2, -1)
Answer:
The length of 
is 48.
Step-by-step explanation:
A square is a quadrilateral whose four sides have the same length and four internal angles have the same measure. The sum of measures of internal angles in quadrilaterals equals 360°. Let 
and 
, the value of 
is:
And the length of 
is:
The length of is 48.
For this case we have that by definition the mass is given by:
Where,
- <em>D: density
</em>
- <em>V: Volume
</em>
The volume of a pyramid is given by:
Where,
- <em>A: area of the base
</em>
- <em>h: height
</em>
Substituting values we have:
We now calculate the mass:
