70.5
84
Step-by-step explanation:
Firstly, we need to sort this list of numbers in order to perform calculations on it.
To find the mean we must add up and divide by the amount of numbers there are.
To find the median we must find the number in the middle of the set.
As there are two numbers in the middle positions, 69 and 72.
We must take the average of these two numbers to determine the middle.
The most is the most common number, which is 84.
<u>Given</u>:
Given that the side length of the cube is 1.8 cm
We need to determine the lateral surface area of the cube.
<u>Lateral surface area of the cube:</u>
The lateral surface area of the cube can be determined using the formula,
where a is the side length.
Substituting a = 1.8 in the above formula, we get;
Squaring the term, we get;
Multiplying, we get;
Thus, the lateral surface area of the cube is 12.96 cm²
