IM SORRY I CANT HELP YOU ONE THIS ONE SORRY I HOPE THIS HELPS :)
Scale factor is used by architects or engineers to transfer their prototype idea to large-scale use. If the volume of a prism is 20, you need to multiply its dimensions with a scale factor to find the new volume which is 540. For example, if the volume is doubled, this means you used a scale factor of 2. Hence, you just have to divide the new volume by the smaller volume.
Scale factor = 540/20
Scale factor = 27
The ratio of areas is the square of the scale factor, so that factor is
√(320/180) = 4/3
