Ritas room is of a rectangular prism. it is 12 feet long,10 feet wide, and 8 feet high. what is the surface area of ritas room?

*Hint: The formula for finding the surface area of a rectangular prism is SA = 2 (wh + lw + lh).

Now, just plug in and solve.

SA = 2 [(10)(8) + (12)(10) + (12)(8)]
SA = 2 (80 + 120 + 96)
SA = 2 (296)
SA = 592.

The surface area of Rita's room is 592 feet squared.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
