E.

The dimension of the smaller cube is 0.2.

Along the side of length 1m we can place 5 cubes.
These 5 cubes can be placed along the side of length 1m 5 times. Hence 5*5=25 cubes in one row.
These 25 cubes can be placed 2/0.2 times along the height. Hence total number is cubes are 25*10=250

1/0.2 = 5 & 2/0.2 = 10
Dimensions are 1 * 1 * 2
number of cubes will be = 5 * 5 * 10 = 250
E

Box's total volume / one cube's volume = number of cubes

Box's total volume: 1 * 1 * 2 = 2 $$m^3$$

Each cube's volume: .2 * .2 * .2 = .008 $$m^3$$

$$\frac{2}{.008}=\frac{2,000}{8}=250$$ cubes
