Answer:
66.08
Step-by-step explanation:
First find the markup
56 * 18%
56*.18 =10.08
Add this to the original price
56+10.08
66.08
This is the cost in the store
![log_{10}(2) \times log_{10}(3)](https://tex.z-dn.net/?f=%20log_%7B10%7D%282%29%20%20%20%5Ctimes%20%20%20log_%7B10%7D%283%29%20)
in log multiplication means addition
hence we add giving us
![log_{10}(2 + 3)](https://tex.z-dn.net/?f=%20log_%7B10%7D%282%20%2B%203%29)
![= log_{10}(5)](https://tex.z-dn.net/?f=%20%3D%20%20log_%7B10%7D%285%29%20)
Most of the time it will be Length x Width x Height.
