Question

What is the surface area of the composite figure?

Answer 1

I'm confused because usually with composite figures I just split the shapes into however many, and apply the formulas to each seperate shape. However, the top rectangle has two lengths, 10cm and 12cm. I don't know what to do with them both.

The formula I'm using is for the surface area of a rectangular prism:
SA = (2LW) + (2WH) + (2LH)

Answer 2

i think it would be 136 based off some attempted math with the formula but im not sure...
nobody is helping wahhh

Answer 3

im be right back have to do something real quick

Answer 4

hello

Answer 5

since the given composite figure is the sum of two figures, and both the figures of cuboidal shape, so The TSA of the composite figure will be given as:
TSA of composite fig = 2[lb+bh+hl}+ 2[lb+bh+hl}
= 2[12*2+2*2+2*12}+ 2[4*2+2*2+2*4}
= 2[24+4+24}+ 2[8+4+8}
= 2*52+ 2*20
= 104+ 40
= 144 square units

Answer 6

whats the tsa

Answer 7

Total surface area

Answer 8

TSA is stand for TOTAL SURFACE AREA

Answer 9

brb again

Answer 10

ok

Answer 11

you're saying the answer is 144?

Answer 12

I think it is 136! :D

Answer 13

IT IS 136!!
Good job buddy! @danijo1814

Answer 14

The picture is like a trick question because half of the top of the smaller rectangle is covered and you have to remember to subtract that from the overall surface area.
