Answer:
16.
Step-by-step explanation:
The formula for a triangle is [tex]\frac{1}{2} * b * h[/tex]
So, we take the triangle we see and but in in the formula.
[tex]\frac{1}{2} * 2 * 3 = 3.[/tex]
Multiply that by 4, because there are four triangles that size.
[tex]3 * 4 = 12.[/tex]
Now, we multiply 2 times 2 because that's the surface area for the bottom.
[tex]2 * 2 = 4.[/tex]
Now, we add the two.
[tex]12 + 4 = 16.[/tex]
