MEDAL AND FAN!!!! What is the lateral area of the rectangular prism? Assume the prism is resting on its base. A. 200 in2 B. 180 in2 C. 90 in2 D. 50 in2 http://lv.k12.com/mediaFiles/Ninth_Grade/Math/Unit17866/Lesson69400/VHS_PA_S2_05_L210_L310_LQ_Q2.gif

Formula: \(LA = (2l + 2w)h\) Plug in what we know: \(LA = (2(4) + 2(5))(10)\) Simplify that. @lordoftanks

OpenStudy (anonymous):

hmmmmm what does la mean

OpenStudy (anonymous):

Lateral area

OpenStudy (anonymous):

Ignore that

OpenStudy (anonymous):

Just simplify: \((2(4) + 2(5))(10)\)

OpenStudy (anonymous):

130

OpenStudy (anonymous):

Check again.

OpenStudy (anonymous):

90

OpenStudy (anonymous):

No..first multiply 2 * 4 and 2 * 5

OpenStudy (anonymous):

180

OpenStudy (anonymous):

180?

OpenStudy (sleepyjess):

What is 2*4?

OpenStudy (sleepyjess):

nvm, yes, 180

OpenStudy (anonymous):

Yes, 180 is correct.

OpenStudy (anonymous):

That's our answer.
