our lines of symmetry is made limited by the presence of the pentagon. If we slice the pentagon into two, the only line of symmetry we could create would be the line intersecting O and the median of LM. Other lines would not create a symmetrical half.
Therefore the line of reflection is only 1.

Fact #1:
A cube has six faces.
Fact #2:
Every one of them has the same area.
Fact #3:
The surface area of each face is (the length of the cube's side)²
Now that I look at this one more carefully, the only thing you need to know
to solve it is Fact #3. (But you can keep the others and save them for later.)
The surface area of each face is (the length of the cube's side)²
64 is the (length of the cube's side)²
Can you find a number that gives you 64 when you multiply it by itself ?
That's the length of the cube's side.
Hint: If you don't get ' 8 ', work on it a little more.
Answer:
bc they are placed the same if one is multiplied by 10. or you could just multiply the tens place and add that to your 100
140=14×10 and 100 and 4 tens is written 140.
