Do you know the formula for surface area of a prism?

OpenStudy (winsteria):

not really

TheSmartOne (thesmartone):

Search it up and tell me what you get.

OpenStudy (winsteria):

(b is the shape of the ends) Surface Area = Lateral area + Area of two ends (Lateral area) = (perimeter of shape b) * L Surface Area = (perimeter of shape b) * L+ 2*(Area of shape b)

TheSmartOne (thesmartone):

so basically this is the formula: surface area of a prism = 2 x area of base + perimeter of base x H

OpenStudy (winsteria):

okay

TheSmartOne (thesmartone):

brb

OpenStudy (winsteria):

how do I set up the problem please help me when you get back lol

OpenStudy (winsteria):

@TheSmartOne

TheSmartOne (thesmartone):

soo I'm back lol

TheSmartOne (thesmartone):

\(\sf\Large Surface ~Area = ( 2 \times B) + (2 \times P)\) The base is anything we want, lets chose 3x 10 recatangle as the base

OpenStudy (winsteria):

okay

TheSmartOne (thesmartone):

so the area of the base is 3 x 10 =? and the perimeter is 2( 3+10) = ?

OpenStudy (winsteria):

3 x 10 = 30 2 (3+10) = 26

TheSmartOne (thesmartone):

so now 2 (10) + 2 (26) = ?

OpenStudy (winsteria):

72

TheSmartOne (thesmartone):

correct (:

OpenStudy (winsteria):

so yeah that's the answer?

TheSmartOne (thesmartone):

yes, np (:
