Just multiply all of them because Volume = Length x Width x Height. So it's 8.5 x 4.5 x 3.75. That equals 143.4375. Cubic inches is just there after you multiply, so you don't have to convert anything. So it's 143.4375 cubic inches.
        
                    
             
        
        
        
Given parameters: 
Weight of Tan  = 146pounds
Unknown: 
Weight of Minh = ? 
Following this problem step wisely, we can derive a solvable algebraic equation; 
   Let the weight of Minh  = M 
In the second sentence, we see that Minh weighs 15pounds more than Tan; 
     So; 
               M  = 15 + Weight of Tan
Since we already know the weight of Tan, 
   Weight of Minh  = 15 + 146  = 161pounds
We clearly see that Minh's weight will be 161 pounds.
