Answer:
<h2>294mm²</h2>
Step-by-step explanation:
Surface Area = Sum of Area of all shapes.
There are 6 cubes which have a length of 7mm.
Area = L * L
Area = 7 * 7
Area = 49mm²
Surface Area = Area of 1 square * Number of Squares
Surface Area = 49 * 6
Surface Area = 294mm²
All angles would have a sum of 180 degrees, so 180-140 is 40. And if you divide 40 by 2, the two side angles will be 20 degrees.
