A gift box is 14 inches long, 8 inches wide, and 4 inches high. How much wrapping paper is needed to wrap the gift box?
2 answers:
Answer:
Option C is correct
The wrapping paper is needed to wrap the gift box is, 400 in²
Step-by-step explanation:
Surface area of the prism(S) is given by:
where, l is the length , w is the width and h is the height of the box receptively.
Given that:
A gift box is 14 inches long, 8 inches wide, and 4 inches high
⇒ l = 14 inches, w = 8 inches and h = 4 inches
Substitute these in [1] we have;
Therefore, wrapping paper is needed to wrap the gift box is, 400 in²

The bottom cutoff heights to be eligible for this experiment is 66.1 inches.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean of 69.0 inches and a standard deviation of 2.8 inches.
This means that
What is the bottom cutoff heights to be eligible for this experiment?
The bottom 15% are excluded, so the bottom cutoff is the 15th percentile, which is X when Z has a pvalue of 0.15. So X when Z = -1.037.
The bottom cutoff heights to be eligible for this experiment is 66.1 inches.
