The volume of a cube with edge of length 2 meters is 2x2x2=8 cubic meters
The volume of a cube with edge of length 4 meters is 4x4x4=64 cubic meters
8/64=1/8=12 1/2%

The Answer Is A)
Volume With an Edge Of 2 Meters = 2^3 = 8
Volume With An edge of 4 Meters = 4^3= 64
Percentage = (8/64) *100 = 12.5 %

First, let's find the volume of the two cubes.
edge length 2 meters: V = 2x2x2 = 8 cubic meters
edge length 4 meters: V = 4x4x4 = 64 cubic meters.
The question asks: 8 is what percent of 64?
Most folks set this up as a simple algebra problem.
8 = p% * 64
Solving,
p% = 8 / 64
= 12.5% or 12 1/2%

The volume of a cube is proportional to the length cubed. The length of the smaller cube is 1/2 that of the larger cube, so the volume will be (1/2)^3 = 1/8 of the volume of the larger cube. 1/8 is 12.5%, so the correct answer is (A).

Sweet baby Jesus, how can you ask this question not in the "homework help" category? Let's see... the volume of a cube is side x side x side. 2 x 2 x 2 = 8, and 4 x 4 x 4 is 64. 8 is 1/8 of 64. 1/8 is 0.125, which is 12 1/2%, which is choice A.
Next time ask a more general question, or at least ask for help in a way that is not "gimmie the answer to this multiple choice homework question."

a) 12 1/2%
cube has l=w=h
cube 1 = 2x2x2 = 8
cube 2 = 4x4x4 = 74
8/64 times 100 = 12.5% or 12 1/2%

A) 12.5%
a cube with and edge of 4 has a volume of 4x4x4=64
a cube with edges of 2 has a volume of 2x2x2=8
8/64=12.5

find the volume of the cube that has the edge of 2 and the volume of the cube that has the edge of 4
V = s^3
V = 2^3
V = 8
V = s^3
V = 4^3
V = 64
8/64 = .125
.125 x 100 = 12.5%
A
