Hello there.
Question: The surface area of the solid is ____ square inches.
Answer: Work out the area of the square first:
7 x 7 = 49in
The formula for area of triangles is:
base x height / 2
7 x 14 = 98
98 / 2 = 49.
There are 4 triangles:
49 x 4 = 196.
Add together the square and triangle areas:
196 + 49 = 245.
Therefore, your answer is 245.
Hope This Helps You!
Good Luck Studying ^-^
