Answer 1

12 square units

Explanation:

Given

See attachment for net

Required

The surface area

The net has the following shapes:

• 1 Square: (Length =2)
• 4 congruent triangles (Base = 2; Height = 2)

So, the surface area is:

Area = Area of Square + 4 * Area of 1 Triangle

`Area = 2 * 2 + 4 * (1)/(2) * 2 * 2`

`Area = 4 + 8`

`Area = 12`
