Question

*ANSWER PLS, DIFFICULT QUESTION* Wrapping paper costs $0.025 per square inch. If a moving box that is an 8 ½ inch cube is being wrapped, how much would the wrapping paper for this box cost (rounded to the nearest dollars and cents)?

Answer 1

Answer: D $10.84

Step-by-step explanation:

If the box is a cube and paper is needed to wrap it, then we need to find the surface area of the box then multiply it buy the cost of the wrapping paper.

The surface area of a cube uses the formula 6a^2  where a is any side length.

We know that the box has a side length of 8.5 inches.

SA = 6*8.5^2

SA= 433.5  

Now multiply the surface area by the money.

433.5 * 0.025 = 10.8375  

Round 10.8375 to dollars and cents as it is required.

10.8375 = 10.84

Which means it will cost $10.84 to wrap the box.
