there is not a scale factor provided.
rule of thumb
perimeter, length, etc.
1- dimensions scale factor increases (scale factor)^1
think of answers ft, yd, etc.
area
2-dimensional (l x w) each dimension will increase by the scale factor. in this example, scale factor of 2.....(2l x 2w) increase by 2^2 or 4
increased by (scale factor)^2, think of answers given as ft^2, yd^2
volume
3-dimensional (l x w x h), each dimension will increase by the scale factor. in this example, scale factor of 2.....(2l x 2w x 2h) increased by 2^3 or 8
increases by (scale factor)^3, think of answers given as ft^3, yd^3
Hope this helps!! Happy Studies.
