60=10√(y-3)
60²=(10√(y-3))²
3600=100(y-3)
3600=100y-300
100y=3600+300
100y=3900
y=3900/100
y=39

we have to chek the possible answer:
10√(39-3)=10√36=10(6)=60

Answer: B.  y=39

Identify the surface area of the composite figure. HELP PLEASE!!
Novosadov [1.4K]

Answer:

Step-by-step explanation:

I've already done this question for you. You must be reposting it because the answer was not correct according to the way the computer was programmed to get the answer. I can only think that you don't count the interface between the cube and the larger figure at all. So let's do it that way.

Start with the cube.

The formal equation is Area = 5 * s^2

It has 5 equal sides each one measuring 3 * 3

Area = 5 * 3^2 =                                                                              45

Now go to the other figure

The front and back face measure 14*6*2                                = 168

Left and Right Sides are 2 * 6 * 8                                                 96

Top and Bottom              2 * 14 *8                                              224

Don't count the base of the cube at all so subtract 3*3             -9

Total                                                                                             524

If that does not work, please leave a note at the bottom of this question.
