Answer:

Explanation:

sureface area of rectanglur object is the sum of the six sides

Area = Length x Width

SArea = Top Area + Bottom Area + Front Area + Back Area + Left Side Area

+ Right Side Area

since the top and bottom have equal area = long x wide

the front and back have equal area = long x tall

and both sides have equal area = wide x tall

I summed the bottom front and side areas each times 2

SArea = 2(Bottom Area) + 2(Front Area) + 2(Side Area)

factor out the 2 and added the area formulas for the bottom front

and side

= 2 [ (long x wide) + (long x tall) + (wide x tall)]

= 2 [ (9 x 4) + (9 x 6) + (4 x 6)]

= 2 [ (9)(4) + (9)(6) + (4)(6)]

= 2( 36 + 54 + 24 )

= 2( 114)

= ???? What is 2 times 114 ???? You can finish this part.
