Question

If L = 2 inches, W = 7 inches, and H = 6 inches, what is the surface area of the rectangular prism?

84 in2
144 in2
136 in2
68 in2

Answer 1

Here is the formula: Surface Area = 2(lh) + 2(lw) + 2(wh)

Answer 2

@amigatour this is a prism , not a cuboid
surface area of prism = perimeter of rectangular base * height
= 2*(L+W)*H

Answer 3

okay so 2*2*7 and so forth which is............ 136

Answer 4

:D

Answer 5

\[2*2*7+(2*2*6)+(2*7*6)\]

Answer 6

thanks sorry to waste you guys time. you guys are smart

Answer 7

equals 136

Answer 8

wish i could give you all metals!

Answer 9

Awe thx but i love helping more that even doing school :P lol

Answer 10

Surface Area = 2 (lh + lw + wh)
2 * (2*6) + (2*7) + (7*6) = SA

Answer 11

yeah u r right in this problem total surface area is asked

Answer 12

haha @qdbug your funny｡◕‿◕｡
