Answer 1

@Ahsome

Answer 2

Simply find the areas for each face, then add them together

Answer 3

So, find the area if the triangle that is at the top and bottom, and then find the area of the three rectangles that are on the sides. Then simply add them together

Answer 4

\[SA=2\times TA+H(S_1+S_2+S_3)\]
Where:
\(TA\) Is the Area of the triangle
\(S_1\) Is one side of the triangle
\(S_2\) Is the second side of the triangle
\(S_3\) Is the thirdside of the triangle

Where:\[TA=\sqrt{p(p-S_1)(p-S_2)(p-S_3)}\]\[p=\frac{S_1+S_2+S_3}{2}\]

Answer 5

Calculate P first. Then TA. Then \(H(S_1+S_2+S_3\)) Then add that to \(TA\)

Answer 6

is it A
