Question

Find the total Area

Answer 1

Correct me if I'm wrong, but it sounds like you're trying to find the surface area of that shape, and not the volume. Do you know how to find the area of a triangle? Area = 1/2 * base * height. Since you're already given the sides for each triangle, you have the base part done. You now just need to find the height of each of these triangles. To do this, you have to break them down into right triangles, where you know one side and the hypotenuse, but you need the last side. You can use the pythagorean theorem to figure that out. Does that make sense?

Answer 2

Yes that is correct, I got:
a²+6²=10²
a²+36=100
-36 -36

a²= 64
√64= 8
36*8= 288
288/ 2 = 144

Answer 3

Thank you so much

Answer 4

Can you explain turn the Total area into the form with √ in it

Answer 5

Ok, great job! Next, you need to do what you did up there with all three sides of the pyramid, then add all your answers together.

Answer 6

Sorry, all four sides of the pyramid. You do know that three of the sides (the top ones) are equal, so really all you need to do is find the area of the base.
