<h3>What is rotational
symmetry?</h3>
It should be noted that rotational symmetry simply means when an object is rotated on its own axis.
In this case, it should be noted that the rotation symmetry that an equilateral triangle has is 3.
Also, the number of degrees that you can rotate the shape to carry it onto itself will be 60°, 120°, and 180°.

To find how much wrapping paper Taylor needs, we can find the total surface area of the rectangular prism.
= 2(18)(9) + 2(18)(4) + 2(9)(4)
= 2(162) + 2(72) + 2(36)
= 324 + 144 + 72
= 540in.²
So, Taylor will need 540in.² of wrapping paper to wrap the gift.
Best of Luck!
An easy way (you must put the numbers in the correct side)
3 2 you cant subtract 5 from 2 so u carry one
-1 5 the 3
2 ¹3. it should look like this.Now u do 13-5=8
-1 5
2 ¹3. now u do 2-1=1
- 1 5
= 1 8
your final answer is 18.
