Answer:
V = 288 

Explanation:
To find the volume of the rectangular prism use this equation:
V = l*w*h
l = length 
w = width 
h = height
Now, lets assign all the variables to the numbers on the picture: 
l = 12 ft 
w = 4 ft 
h = 6 ft 
Plug these into the equation and solve 
V = (12 ft)(4 ft) (6 ft) 
V = 288 

So, the volume of the rectangular prism is 288
