Question

What is the surface area of the composite figure?

Answer 1

Break the composite figure into two rectangular prisms

Find the surface area of each prism, then add up the two surface areas

You'll have to subtract out the part where the two prisms are connected since that's not on the outside.

Answer 2

one sec while I draw it out

Answer 3

Okay...

Answer 4

here's what you get when you break up the two figures

Answer 5

so find the surface area of each prism, but remember to subtract off the areas of those red regions since they aren't on the outside of the composite figure

Answer 6

Answer 12

what did you get for the answer?

Answer 13
