Alright and what is the length and width of one side of this cube?

i wanna say 5?

axie:

Yup! So how do we find the area of one section?

multiply them all together?

axie:

Kinda, we would multiply 5x5 to get the surface area of one section. But we have 6 sections so technically it would be (5x5)x6

Yes

axie:

Any questions

karissafrazier:

so i do this for 5 sides?

axie:

No. We already found the surface area, gimme a second

so (3*4*2)*6?

axie:

Basically what we are doing is finding the area of every little shape from the shapes map and and adding then together

karissafrazier:

??????? that confuses me even more😭

|dw:1694635757238:dw| Just imagine that this is a perfectly drawn square and the a's are perfectly written. The way you find the surface area of a square is multiple its length, by its width. Since the sides of a square are all equal, we denote that as \[SA_{s} = a \times a = a^2\] The surface area of a square is equal to a times a, or a squared. Now to find the surface area of a cube, we must first determine what equation to use. A cube has six sides, and all the sides are squares. So in order to find the surface area of the cube, we simply do \[SA_{c} = 6 \times a^2 = 6a^2\]

For the rectangular prism, @karissafrazier try see if this helps you visualize it.
