Question

A room in the shape of a rectangular prism measures 15 feet by x feet by 12 feet. Write a simplified expression for the volume (in cubic feet) of the room.
Volume = ft3

Answer 1

Answer: Volume =$180x\ ft^3$

Step-by-step explanation:

We know that the volume of a rectangular prism is given by :-

$V=length\times width \times height$

Given : A room in the shape of a rectangular prism measures 15 feet by x feet by 12 feet.

Then, the volume of a rectangular prism will be :-

$V=15\times x\times12\\\\\Rightarrow\ V=15\times12\times x\\\\\Rightarrow\ V= 180x$

Hence, the simplified expression for the volume (in cubic feet) of the room will be : $180x\ ft^3$

Answer 2

180x feet^3

this is the answer because volume is lwh so 15 x 12 x x is 180x the labeled is 180x ft.^3
