Answer:
9m
Step-by-step explanation:
The surface area of a cube is given by
SA = 6s^2 where s is the side length
We know the surface area is 486 and the side length is z
486 = 6z^2
Divide each side by 6
486/6 = 6z^2/6
81 = z^2
Take the square root of each side
sqrt(81) = sqrt(z^2)
9 = z
Each side has a length of 9m
The number of ways for which she could pick four colours if green must be one of them is; 10 ways.
<h3>How many ways can she picks four colours if green must be there?</h3>
It follows from the task that there are 6 colours in total that she could pick from.
Hence, since she needs four colours with green being one of them, it follows that she only has 3 colours to pick from 5.
Hence, the numbers of possible combinations is; 5C3 = 10 ways.
