Help help help help help help find surface area​

Answer 1

Remember, you find the area of triangles by multiplying the base/height and then dividing it by 2.

First let's find the base.

128x96=12288

Now multiply by the height.

12288x80=983040

Final step:

Divide by 2.

983040/2=491520 cm.

In turn, this makes 193512 inches.
