Based on the calculations, the volume of this louvre pyramid is equal to 8,983 cubic meter..
<u>Given the following data:</u>
Base width = 35 meters.
Height = 22 meters.
<h3>How to calculate the volume of a pyramid?</h3>
Mathematically, the volume of a pyramid can be calculated by using this formula:
Volume = 1/3 × base area × height
For the base area, we have:
Area = w²
Area = 35² = 1,225 m².
Substituting the parameters into the formula, we have;
Volume = 1/3 × 1,225 × 22
Volume = 1/3 × 26,950
Volume = 8,983 cubic meter.

The confidence interval is from 9.81 to 10.19.
We first find the mean of the data:
<span>(9.8+10.2+10.4+9.8+10.0+10.2+9.6)/7 = 10
Next we find the standard deviation:
</span>σ=√([<span>(9.8-10)^2+(10.2-10)^2+(10.4-10)^2+(9.8-10)^2+(10-10)^2+(10.2-10)^2+(9.6-10)^2]/7) = 0.262
The z-score for 95% confidence is found by
1-0.95 = 0.05; 0.05/2 = 0.025; from the z-table, it is 1.96.
The confidence interval is calculated using
