Show that if p(a) ⊂ p(b) then a ⊂ b. 
<span>I will assume p() means power set. </span>
<span>proof: let x∈a, then {x} ∈ p(a) and so by hypothesis {x} ∈ p(b). However {x} could not be in p(b) unless x∈b. This shows that each element of a is an element of b and hence a ⊂ b.

I think she can add 5p more of orange which is 9p and 6p more water which is 8p. I'm pretty sure this works because 9 is the next closest multiple of 3 and 8 is one number less than that. Hope this helps!
        
             
        
        
        
16 m³
Step-by-step explanation:
Step 1:
Here we are going to find the volume of square pyramid.
Volume of square pyramid =  ×
 ×  ×
 × 
Here base = 4 m
          Height = 3 m
Step 2:
Volume = (1/3) × (4 × 4) × 3
               = 16 m³
