To solve the problem we must know about Z-Score.
<h3>What is Z-score?</h3>
A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,

Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
The life span of an appliance that has a z-score of –3 is 24 months.
Given to us
- Mean, μ = 48 months,
- standard deviation, σ = 8 months,
- Z-Score = -3
<h3> What is the life span of an appliance?</h3>
The life span of the appliance can be calculated using the Z-score formula,

Substitute the values,

Hence, the life span of an appliance that has a z-score of –3 is 24 months.

The volume of box B is (A) 864 cubic meters.
<h3>
What is volume?</h3>
- The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity.
- For example, the space occupied or contained by a substance or 3D object.
- Volume is frequently mathematically quantified using the SI-derived unit, the cubic meter.
To find the volume of box B:
- We have been assigned a volume of 32 cubic meters.
- The cubic root of 32 yields the box's dimensions, which are 3.1748 x 3.1748 x 3.1748 meters.
- Meters when the dimensions are tripled: 9.5244 x 9.5244 x 9.5244
= 864 cubic meters.
Therefore, the volume of box B is (A) 864 cubic meters.
