Answer:
D. 340 square inches
Step-by-step explanation:
Side length translates to 1 side of the square, so you do 10 x 10 to find the area of the square.
10 x 10 = 100
The triangle one isn't much more difficult. The formula for finding the area of a triangle is bh1/2
So:
10 x 12 = 120/2=60
From there just multiply the result by 4- the amount of triangles on the square pyramid, and you'll get your answer.
60
x 4
240 + 100 = 340 square inches
