In this problem your going to need to find volume.
The formula for volume of a rectangular prism (Which is what we are trying to find)
Is Volume = Length x Height x Width
So in your problem we can create the equation:
7 x 4 x 12 = Your answer.
7 x 4 = 28
28 x 12 = 336.
Your going to need 336 feet^3 (D)
Hope this helps!

Answer: your answer is 195
Step-by-step explanation:
Answer:
Proportionality Constant = k = 
Step-by-step explanation:
Equation is:

=> 
Comparing it with
, where k is the proportionality constant, We get:
Proportionality Constant = k = 
It looks like you're doing good with breaking-down the composite into digestible pieces. So, don't stress too much!
Keep in mind that the area for a 3D shape is Bh, where "B" is the area of a face & "h" is the height.
#5
Shape A is 3X4X9.
First, calculate the area of a face:
9X4= 36
Multiply by height:
36X3= 108
The process is the same with shape B.
3X4X8
Calculate area of face:
8X4= 32
Multiply by height:
32X3= 96
Now you add both areas:
108+96= 204 cubic feet
I think you're doing pretty good, just don't over think things too much. Try #8 with the similar process seen here. Just comment if you get stuck.
Hope this helps!
