Answer:
40 units²
Step-by-step explanation:
Surface Area of a square pyramid = b² + 2bl, b = 4, and l = 3
=> (4)² + 2(4)(3)
=> 40 units²
Hope this helps!
4 x 4 = 16(area of base below *square*)
3 x 4 = 12, 12 divided by 2 ( x 1/2) = 6(area of one triangle side), 6 x 4 = 24(area of 4 triangles on all sides
Adding all given areas:
16 + 24 = 40 squared.
