The cube with twice the width has 8 times the volume of the first cube. Lets say Cube1 has width A lets say Cube2 has width 2*A so V1 = A cubed V2 = (2*A) cubed so A = the cubed root of V1 so V2 = (2 * (the cubed root of V1)) cubed so V2 = 2 cubed * V1 so V2 = 8 * V1
To find the scale factors of two objects, you need to compare the ratios of things like their sizes, areas, volumes, and length. For example, if one is given a volume of 7 for a shape, and a second shape has a volume of 14, you have to compare the volume ratio of these two shapes to find the scale factor. This scale factor is 1 to 2, or the volume of the second shape is twice the first one. Scale factors are useful for scale drawings.

The ratios of areas are the squares of the ratio of lengths (and the ratio of volumes are cubes of the ratio of lengths). As the perimeter of the second is twice the perimeter of the first, each length of the second is twice the length of the first, and so the ratio of the lengths is 1:2 Thus the ratio of the areas is 1²:2² = 1:4. Therefore the surface area of the larger prism is four times that of the smaller prism.

Canada is the second largest country after Russia. Although, Russia is almost twice the size of Canada.

There are 6 white cubes and 3 green cubes. Algebraically, the equations are W = white cubes, G= green cubes W+G = 9 and W = 2G so substituting we have 2G + G = 9, and 3G = 9, so G=3 and W=6.

The ratio of the volumes of two similar solids is proportional to the cube of the diameter - or of any other linear measurement. For example, at twice the diameter, you would have 8 times the volume.
