Answer: Square pyramid
Step-by-step explanation: In this problem, we are asked what three-dimensional figure can be formed from the given net. A net is the shape formed when a three-dimensional shape is unfolded.
A net is made up of all of the faces of a three-dimensional figure that make up the surface area.
To determine what kind of three-dimensional figure can be formed using this net, first notice that the net has four triangular faces and one square base. The four triangular bases tell us that it's a pyramid and the square base tells us that it's a square pyramid.
Therefore, the net shown here can be folded to form a square pyramid.
