Answer:
2,744 feet³
Step-by-step explanation:
Volume = Length * Width* Hight
A cube has all the sides equal in measure so Length and Width and Hight are equal and are given in the picture to be 14 feet. 
V = 14 *14*14 = 2,744 cubic feet
 
        
             
        
        
        
Answer:
30.56 yd²
Step-by-step explanation:
To determine the area of the composite shape, we need to:
- Divide the shape into two smaller "known" shapes (Refer to image). 
- Determine the area of those "known" shapes. 
- Add the area of the known shapes to obtain the area of the figure.
<u>Determining the area of shape 1 (Rectangle 1):</u>
⇒ Area of rectangle = Lenght × Breadth
⇒                               = 2.1 × 4.8
⇒                               = 10.08 yd²
<u>Determining the area of shape 2 (Rectangle 2):</u>
⇒ Area of rectangle = Lenght × Breadth
⇒                               = 6.4 × 3.2
⇒                               = 20.48 yd²
<u>Determining the area of the figure:</u>
⇒ Area of figure = Area of rectangle 1 + Area of rectangle 2
⇒                         = 10.08 + 20.48
⇒                         = 30.56 yd²
