Answer:
$4000
Step-by-step explanation:
Given that :
Volume of cube = 8000 ft³
Charge per ft² = $10
Recall, volume of a cube = a³
Where a = edge 
Hence, 
a³ = 8000
Take the cube root of both sides 
a = 20
Hence, 
Volume = 20 * 20 * 20
The Area of the floor will be :
20 * 20 = 400 ft²
If charge per ft² = $10
400 ft² = ($10 * 400) = $4000
 
        
             
        
        
        
Take the 25 art projects devised by 100% would be .25 then multiply .25 by the percentage that got perfect scores in which you would get 3 perfect scores
.25x12=3
        
                    
             
        
        
        
The equation in slope intercept form is y=-x-5
