The Surface Area Of A Rectangular Prism!
Surface area is all of the areas on all of the sides added up on a solid figure such as ( in our case) a rectangular prism.
This is called a net. ---------------------> Nets are made out of shapes like this cube.
This is how you would change a cube into a net:
Heres how to get the surface area of a rectangular prism:
We know that there are two 6cm squared, two 2cm squared and two 3cm squared.
This is what it looks like: ( don't forget the formula)
2(6cm squared) + 2 (6cm squared) + 2 (3cm squared) Now do some math
36cm squared + 4cm squared + 9cm squared =
A longer way to do it is like this:
(6x6) + (2x2) + (3x3)
36 + 4 + 9 =
Volume Of A Rectangular Prism
Lets say that we are trying to find the volume of a rectangular prism.
L = 6
W = 2
Here's how you solve it.
L x W x H = (6cm squared x 2cm squared) x 2 cm squared =
24 cm squared.
Multiple methods to show this are
Length x width x height ( height also known as depth)
or you could use
Area of base x height
