Answer:

5.6 cm

Step-by-step explanation:

As you can see in the picture, there is a right triangle formed. The right angle is opposite the 6.5 cm side, so that is the hypotenuse, and the other sides are the two legs. The side we do not know in the right triangle is the height of the pyramid.

We know that a²+b²=c² for a hypotenuse c and two legs a and b in a right triangle.

height²+3.3²=6.5²

subtract 3.3² from both sides to isolate height²

31.36 = height²

square root both sides to isolate height

height = 5.6 cm

I don't know the answer but my tip would be to split the shape the way I did it, find the lengths of each side, and then find the area for each individual shape.

Then add all the areas together.
