Given the conversion factor 3.28 ft / 1m which cube above has the larger surface area

cube A is 7' cube b is 2m

The first thing that we are going to do in passing everything to the same unit.

We have then:

Cube A:

7 * (1 / 3.28) = 2.13 m

Cube B:

2 m

The surface area of a cube is:

A = 6 * L ^ 2

Where,

L: side

Since cube A has a longer side (2.13m) then it will have the largest surface area.

Answer:

Cube A has the larger surface area
