Answer 1

408in
`^(2)`

Explanation:

1.) First, find the area of the base (**If you don't know how to do this, just find the length and width, then multiply them together). Since there aren't any other measurements, I'm guessing all sides are 12 inches (12x12=144).

2.) Next, find the area of the triangle. Use 12 and 11 as your measurements in this case (12x11=132).

3.) Now, divide your answer from step 2 (132) by 2 (132/2=66). This is because usually, triangles are HALF of the area of a square. If you skip this step, you will have made a cube instead of a pyramid.

4.) Multiply the answer from step 3 (66) by 4 (66x4=264), since there's 4 triangles on the pyramid.

5.) Add the answer from steps 4 (264) and 1 (144). This should get you the TOTAL surface area (408in
`^(2)`).
