Answer: D) 32
Each side of the cube is 8 units, so the perimeter of one side is 4*8 = 32.
You have to use PEMDAS (Parentheses Exponents Multiplication/Division Addition/Subtraction) to solve this,
Because you don't have any parenthesis or exponents you start with Multiplication/Division. This means you do 4*3 to get 26+5-12
Then, you move to Addition/Subtraction in which you complete left to right, So you do 26+5 to get 31-12
Finally you subtract 31-12 to get 19
Answer:
Step-by-step explanation:
