Answer:
Step-by-step explanation:
we know that
In the right triangle of the figure XYZ
Applying the Pythagorean Theorem
substitute the given values
square root both sides
There are 360 degrees in the rhombus which means the equilateral triangles has 180 degrees (because it is half the rhombus and also it is the angle sum of a triangle). It is equilateral meaning all sides and angles are the same so they all must be 60 (180/3)
Now this must mean that angle a is equal to the opposing angle being 60
Answer:
Edge = 12
Total Surface Area = 72
Step-by-step explanation:
Volume of the cube = 1728
Length of the edge =
We know that
TSA (Total Surface Area) =
where a = length of edge of cube
So,
TSA of cube =
