Answer: 
Step-by-step explanation:
A rectangular prism is a three-dimensional solid.
A rectangular prism has six faces (each one of these faces are rectangles), eight vertices and twelve edges.
You know that this rectangular prism has 5 layers and the volume of one of these layers is 18 cubic centimeters (
).
Assuming that all these layers are equal, the volume of this rectangular prism can be calculated with:

Where
is the volume of one layer.
Substituting, you get:

Answer:
A and B
Step-by-step explanation:
Given
8 > 3 + 
Isolate the term in t by subtracting 3 from both sides
5 >
( multiply both sides by 4 )
20 > t ⇒ t < 20
t = 12 and t = 16 are both less than 20
Hence A and B
