A rectangular prism has a base that is 6 meters by 3.5 meters, and the prism is 9 meters high. What is the surface area of the prism?

213 m^2

Step-by-step explanation:

The surface area for a rectangle prism is given by

A=2(wl+hl+hw)

We know the base is 6 meters by 3.5 m  so l = 6 and width =3.5

The heigth is 9 m

A = 2 ( 6*3.5 + 9* 6 + 9* 3.5)

   = 2 * (21 +54 +31.5)

    = 2*(106.5)

    =213 m^2

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
