Plz i need srs . i will give u a brainlest and im giving out extra points

The last time you asked this question, I showed you how to find the area of the shown sides, which came to equal 440 square inches. The question says to not include the base, but you might have to include the top, which is a 10x12 rectangle. Add 10*12 (120) to 440 to get 560. I hope that helps!

10 x 20 = 200

12 x 20 = 240

10 x 12 = 120

i think your surface area should be 560 sq inches
