How will the volume of a prism change if its height is multiplied by a scale factor of 4?
Fynjy0 [20]

Answer:

It will double in size, as M x M x M x M  is simply just 3 changeable values. When we change 4 numbers of a prism (3 changed values ) to all 4 we have a S4 value to the volume, But we didnt do this, applying x 4 to either measurement it can only increase the volume by x 2. We had a one change value SF4 so we have SF 2= double. That means if we have two change value value SF4 we have 3 = 3 x total  increase, if we have a three input change by SF4 we can increase size to 4x total increase.
