Answer 2

the volume in this case is h*w*l
(height times width times length)

if you scale by 3 then th enew dimensions are
3h * 3w *3l

how many times bigger is this than h*w*l?

Answer 3

@mrnood its 1890

Answer 4

when you scale linear features by n the areas increases by n^2, and the violume increases by n^3

in this case n is 3 so the volume increases by factor od 3^3 = 27

70*27 =1890 so you are correct
