Your coffee shop is 36 meters long

Good Luck! :)

Find the volume of a box 24 in. x 20 in x 23 in.
kaheart [24]
<span>The definition for discovering the volume of a box is when the person takes the length, the width, and the height of the box. And because we have those values here, there is no math that is necessary to do other than multiplying the numbers together and creating a new unit of inches cubed. The answer is 11040 inches cubed.</span>
