The volume of the complex figure shown in the diagram is 56 m³.
<h3>
Volume</h3>
Volume is the amount of space occupied by a three dimensional object.
Volume = length * breadth * width
The volume of the big cube = length * breadth * width = 7 * 3 * 4 = 84 m³
The volume of the small cube cut out = length * breadth * width = 4 * 7 * (4 - 3) = 28 m³
Volume of the complex figure = 84 m³ - 28 m³ = 56 m³
The volume of the complex figure shown in the diagram is 56 m³.

Answer:
1 1/8
Step-by-step explanation:
The variance for the sample is 25
For given question,
We have been given the sample size n = 21
and the sum of squares is SS = 500
We need to find the variance for the sample.
We know that the variance is mathematically represented as,
Substituting given values in the above formula,
= 500 / 20
= 25
So, the variance is 25
Therefore, the variance for the sample is 25

The correct answer is 28.3.
You take 22/1.4 and get 15.7142857143. Then you take 15.7142857143*1.8 which equals 28.2857142857 so you round it up to 28.3 which is the answer.
I hope this helps you:)
