Answer:
The lateral height of the square pyramid is 
Step-by-step explanation:
step 1
Find the surface area of the cube
The surface area of the cube is equal to

where
b is the length side of the cube
w have

substitute

step 2
Find the lateral height of the square pyramid
we know that
the surface area of the square pyramid is equal to

where
B is the area of the base
b is the base of the lateral triangle (base of the square)
h is the lateral height of the square pyramid

-----> is the same surface that the cube

substitute the values and solve for h



Answer:
X cannot be decided
Step-by-step explanation:
According to the question,we will start solving the problem by dealing with the bracket first
So let's get to work
2(x-3)=2x+5
Bracket first
2x-6=2x+5
So let's collect like terms
2x-2x=5+6
0=11
Which means the that we can't get the value for x because x has already been eliminated
So to my own understanding there is no definite solution to get the real value of x
I hope you understand
