1- You are designing a new popcorn box in the shape of a rectangular prism for the cinema theatres. The new popcorn box has a length of 7 inches, a width of 4 inches, and a height of 4 inches but does not include a lid.

The surface area is 116 square inches

Step-by-step explanation:

Given

-- Length

-- Width

-- Height

Required

Determine the surface area of the box [Missing from the question]

Since the box has no lid, the surface area is:

Hence, the surface area is 116 square inches

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

answer is x<
