Painted Cubes
Twenty seven identical white cubes are assembled into a single cube,
the outside of which is painted black. The cube is then disassembled
and the smaller cubes are thoroughly shuffled in a bag.
A blindfolded man (who cannot feel the paint) reassembles the pieces
into a cube. What is the probability that the outside of this cube is
completely black?

Answer of 6÷2(1+2) is ...
Here is a simple maths for you..
whats the answer of 6÷2(1+2) = ?
Solution 1:
6 / 2 (1+2) = ?
Step 1: Solve what's inside the parenthesis first
(1+2) = 3
Step 2: Replace values
6/2(3) = ?
Step 3: Solve the division (we must solve it from left to right)
6/2 = 3
Step 4: Replace values, then multiply
3(3) = 9
------------------------------------------------------------------------------------- Solution 2:
Description: This is how we are taught at school, sadly we don't like solving it this way, so we got stuck in solving equations in the simplest way.
Step 1: Write the equation properly
6
- (1 + 2) = ?
2
Step 2: Solve what's in the parenthesis
(1 + 2) = 3
Step 3: Replace
6
- (3) = ?
2
Step 4: In clockwise motion, multiply 6 to the value on its right 6*3 = 18
Step 5: In clockwise motion, divide the answer from Step 4.
18 / 2 = 9
The answer for both solution is "9"
