Answer:
2187.5 cubic meters of water
Step-by-step explanation:
Volume of rectangle = L * W * D
V = 50 * 25 * 1.75
V = 2187.5
 
        
                    
             
        
        
        
6hrs = school
9hrs = sleeps              = 18hrs // 24hrs      ----6hrs left
3hrs = plays
6hrs = other things
playing = 12.5% -- 3/24                 3/24*100
other things = 25% -- 6/24             6/24*100
        
                    
             
        
        
        
Answer:
15.5 ft²
Step-by-step explanation:
The area (A)  of a regular polygon is calculated as
A =  pa ( p is the perimeter and a the apothem )
 pa ( p is the perimeter and a the apothem )
Here side of regular pentagon is 3 ft, thus
perimeter = 5 × 3 = 15, so
A = 0.5 × 15 × 2.06 ≈ 15.5 ft ( to the nearest tenth )
