Question

The volume of a single layer in a rectangular prism is 18 cubic centimeters. There are 5 layers in this rectangular prism. What is the volume, on cubic centimeters, of this rectangular prism?

Answer 1

Answer: $90cm^3$

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 ($18cm^3$).

Assuming that all these layers are equal, the volume of this rectangular prism can be calculated with:

$V_{prism}=5*V_1$

Where $V_1$ is the volume of one layer.

Substituting, you get:

$V_{prism}=(5)(18cm^3)\\\\V_{prism}=90cm^3$
