Answer:

1 m³

Step-by-step explanation:

Given 2 similar figures with sides in the ratio a : b, then

ratios of the volume = a³ : b³

Here ratio of sides = 2 : 8 = 1 : 4, thus

ratio of volumes = 1³ : 4³ = 1 : 64

That is the volume of figure B is 64 times the volume of figure A, hence

volume of figure A = [tex]\frac{64}{64}[/tex] = 1 m³
