Each face is 64 cm^2 because each face is a square, and the area of a square is the length x width.
There are 6 faces
The answer is 384 cm^ 2
If you make both of the denominators the same this can be a lot simpler.
1 1/2 divided by 1/4
1 2/4 divided by 1/4
6/4 divided by 1/4
How many times does 1/4 go into 6/4?
6
Hope this helps :)
The way the question is worded is a little confusing.
I think I would say 10m. It could be 5m, but usually they list length first, then width. The perimeter, the whole distance around the outside, is 30 m (10 + 10 + 5 +5)
For the given geometric series the value of the common ratio(r) is 3, while the value of a₁ is 1.
<h3>What is geometric series?</h3>
A series of numbers whose any two consecutive numbers are always in a common ratio of that series.
Given to us
Series, 1 3 9 27 81
To find the value of the common ratio(r), we will simply find the ratio of any two consecutive numbers, therefore,
![r = ratio = \dfrac{3}{1} = 3](https://tex.z-dn.net/?f=r%20%3D%20ratio%20%3D%20%5Cdfrac%7B3%7D%7B1%7D%20%3D%203)
As we can see the common ratio of the given series is 3, therefore, every next number will be thrice the number before.
We need to find the value of a₁ for the given series, and as we know that a₁ is the first number of the series with which the series is starting, therefore,
a₁ = 1
Hence, for the given geometric series the value of the common ratio(r) is 3, while the value of a₁ is 1.
