Answer:
28 units^2
Step-by-step explanation:
1. First, let's divide this figure into two shapes: a square and a trapezoid. (Look at the image below explanation for division).
2. Next, we should know the area formulas of the square and trapezoid.
- Square:  , where s = side , where s = side
 , where a and b = top and bottom and h = height , where a and b = top and bottom and h = height
3. Solving Area of Square and Trapezoid
 . Area of square is 16 . Area of square is 16
 . Area of trapezoid is 12. . Area of trapezoid is 12.
- 16 + 12 = 28 
Therefore, the area of the figure is 28 units^2.
 
        
             
        
        
        
well, let's notice something, a cube, all equal sides, has a side of 6, thus its volume is simply 6*6*6 = 216 cm³.
now, a rectangular prism, is a cuboid as well, but with varying dimensions.
let's notice something 6*6*6 is simply a multiplication of 3 numbers, let's then do a quick <u>prime factoring</u> of those numbers, well, 6 factors only into 2 and 3, so then the product of 6*6*6 can really be rewritten as (2*3)(2*3)(2*3).
well, regardless on how we rearrange the factors, the product will be the same, commutative property, so the rectangular prism will more or less have the same product and thus just about the same prime factors.
so let's rearrange on say hmmm height = 3 cm, length = 3*3 cm and width = 2*2*2 cm, notice, is still the same prime factors, 3*9*8 = 216 cm³.
Check the picture below.
 
        
             
        
        
        
8^3 = 512
8^3 also eqauls 8 x 8 x 8. 
I hope I helped!
        
                    
             
        
        
        
Answer:
6:12
Step-by-step explanation:
Add 1+2=3
18/3=6
6x1=6
6x2=12
Out it back in the ratio
