What is the surface area of the right rectangular prism? enter your answer in the box. 54 in² a rectangular prism with a length of 3 inches, a width of 1 inch, and a height of 2 inches.

The surface area of the right rectangular prism is, 22 square inches.

Step-by-step explanation:

Surface area of the right rectangular prism(A) is given by:

            ....[1]

where,

w is the width

l is the length

h is the height of the  right rectangular prism respectively.

As per the statement:

A rectangular prism with a length of 3 inches, a width of 1 inch, and a height of 2 inches

⇒ in., w = 1 in. and h = 2 inches.

Substitute these in [1] we have;

A = 2(11)

⇒

Therefore, the surface area of the right rectangular prism is, 22 square inches.

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.
