Answer:

96units^2

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
(2)/(3) , then the corresponding change in area is
(2^2)/(3^2)=(4)/(9) .

the total surface area of the new cube is
=(4)/(9)* 216 .

=96units^2
