Answer: A. 94
Step-by-step explanation:
The formula for surface area is A=2(wl+hl+hw).Wwe are given our values of width, length and height, so we can plug them in.
w=3
l=4
h=5
A=2((3*4)+(5*4)+(5*3))
A=2(12+20+15)
A=2(47)
A=94
We can use the concept of combinations for this particular problem since it was clearly stated that the order in which the selection is made does not matter. By using a calculator, we can obtain the value of 62C6 of 61474519. So, there are 61474519 possible different selections.
