Answer:

$96units^2$

Step-by-step explanation:

The total surface area of a cube is given by $6l^2$ .

The first cube has side length $l=6$ units.

This cube has total surface area, $6(6)^2=216units^2$ .

If the second cube is reduced in size by $\frac{2}{3}$ , then the corresponding change in area is $\frac{2^2}{3^2}=\frac{4}{9}$ .

the total surface area of the new cube is $=\frac{4}{9}\times 216$ .

$=96units^2$
