Answer: Too little information
We need to know how much the butter costs per pound.
Answer: The required simplified answer in standard form is 
Step-by-step explanation: We are given to multiply the following polynomials and write the answer is standard form :

To multiply the given polynomials, we need to multiply each term of one polynomial to each term of the other polynomial.
From (i), we have

Thus, the required simplified answer in standard form is 
Answer:
6 x 6 x 3 cm
Step-by-step explanation:
The base of the box needs to fit the base of the hemisphere.
The maximum width and length of the hemisphere is the diameter of the base of the hemisphere (which is circular)
Diameter of a circle = 2r
As the radius = 3 cm, the diameter = 2 x 3 = 6 cm
Therefore, the width and length of the box should both be 6cm
The height of the box needs to accommodate the height of the hemisphere. The height of the hemisphere is the radius, so the height of the box should be 3 cm.
Therefore, the dimensions of the box should be 6 x 6 x 3 cm
