A rectangular prism is a three-dimensional figure; therefore, the units of measure will be cubed when we find our answer. A rectangular prism also has three dimensions that are required to find the volume: Length, Width, and Height. These dimensions must all be multiplied by each other to find the volume. The values for these do not need to be specific; they can be interchanged at any moment. That being said, let's plug in these values for our variables.
Volume = Length x Width x Height; substitute values.
Volume = 14.7 x 23.4 x 3.2; multiply 14.7 by 23.4 first. This allows our units to be squared (units^2).
Volume = 343.98 x 3.2; multiply these two dimensions. This determines our units to be cubed- and furthermore- our volume.
Volume = 1100.736; remember to apply your proper units.
Your answer for this problem is 1100.736 m^3.
I hope this helps!
