Usually the easiest way to solve this is by using a calculator. Of course only if your teacher allows you too.
The surface area of the cube is 600cm^2.
6(10^2)
6(100)
600
Answer B
There are 16 oz in a pound. 16(2)=32 and there are 4 oz leftover.
The probability that x >17 will be found as follows:
the z-score is given by:
z=(17-15.2)/0.9=2
Thus
P(X>17)=1-P(x<17)=P-(z=2)
=1-0.9772
=0.0228
