Answer:
C
Step-by-step explanation:
using the cosine ratio to find p
cos 45° =  =
 = 
cross- multiplying gives
p × cos45° = 6 → [ cos 45° =  ]
]
p ×  = 6
 = 6
multiply both sides by 
⇒ p = 6 ( third option on list )

Answer:
pictures are in order 
Step-by-step explanation:
 
        
             
        
        
        
Let the Volume of the first cube be V1
V1 = 2 * 2 * 2
 = 8 cm*3
Let the Volume of the second cube be V2
V2 = 6 * 2 * 12
 = 144 cm*3
Now, cube1 with volume of 8 cm*3 holds 468 grains of rice. 
Thus, 1 cm*3 volume can hold 58.5 grains of rice ( 468 / 8 = 58.5)
Cube2 has volume of 144 cm*3. 
Hence, it can hold 8424 grains of rice ( 144 * 58.5 = 8424)
