Question

Use the net to find the lateral area of the prism.

432 m2

270 m2

180 m2

225 m2

Answer 1

since lateral area excludes the top and bottom bases we can simply find the area of the four middle rectangles

Answer 2

if area = Length*width, what is the area of this rectangle?

Answer 3

is it 45

Answer 4

good, let's keep going

Answer 5

area = ?

Answer 6

still there?

Answer 7

yes i am sorry

Answer 8

it would be 45 again

Answer 9

think carefully

if the length is 15 and the width is 6, and area = length*width, area = 15*6 = ?

Answer 10

90

Answer 11

good

now if we look at the other two rectangles, they're the same dimensions as the first two rectangles

so lateral area = 90 + 45 + 45 + 90 = 270 m^2 = your answer

Answer 12

thank you very much
