To get 75 decreased by 40% you subtract 40% from 100%.
100 - 40 = 60
So to get 60% of 75 you multiply .60 by 75.
.60 x 75 = 45
You have $45 now, but you have to decrease it by 40% again. You do the same process, so we need to multiply .60 by 45.
.60 x 45 = 27
So, the final result is $27.
Remember that the surface area of a cube is A=6s^2 since there are 6 sides in a cube and the area of one side of a cube is A=s^2
Given a side length of 11 cm, we do the following:
A=6(11)^2
A=6(121)
A=726
So the surface area is 726 cm^2
