Question

The net of a square pyramid is shown: What is the surface area of the figure? (A)0.7625 square inch

Answer 1

Answer:

C. 0.6625 square inches

Step-by-step explanation:

To get the area of the net of a square pyramid;

We need to find the are of the square base and the area of the four triangles;

Area of the square base = s²

                                         = (0.25 in)²

                                         = 0.0625 in²

Area of one triangle = 0.5 × b × h

                                 = 0.5 × 0.25 in × 1.2 in

                                 = 0.15 in²

Area of the four triangles = 0.15 in² × 4

                                          = 0.6 in²

Therefore;

Area of the net square pyramid = 0.0625 in² + 0.6 in²

                                                     = 0.6625 square inches
