How to find the total area of the solid figure?

OpenStudy (anonymous):

OpenStudy (anonymous):

Okay, you see the big square?

OpenStudy (anonymous):

on the side?

OpenStudy (anonymous):

yes!

OpenStudy (anonymous):

Do you know how to find the area of that?

OpenStudy (anonymous):

yeah, 5 x 6 right?

OpenStudy (anonymous):

A = 2(wl+hl+hw) A = Total Surface Area

OpenStudy (anonymous):

w = 3 l = 5 h = 6

OpenStudy (anonymous):

126 sq ft?

OpenStudy (anonymous):

A=2((3)(5)+(6)(5)+(6)(3))

OpenStudy (anonymous):

A = 2(15 + 30 + 18)

OpenStudy (anonymous):

A = 2(63)

OpenStudy (anonymous):

A = 126

OpenStudy (anonymous):

So 126 is your answer. :)

OpenStudy (anonymous):

Thank you! That helped me so much

OpenStudy (anonymous):

No problem. :D

Do you know how to find the total area of this type of figure?

@jcpd910

OpenStudy (anonymous):

A=2πrh+2πr2

OpenStudy (anonymous):

A = 2(3.14)(3)(10) + 2(3.14)(3)^2

OpenStudy (anonymous):

78 in ^2?

OpenStudy (anonymous):

78 pi *

OpenStudy (anonymous):

correct. :D

OpenStudy (anonymous):
