1 Circle the letter with the correct solution or answer. The total distance around the 2D shape is A volume, B perimeter, C area, D kilometer. 1.2 The name of the 3D object below is A rectangle prism, B triangular pyramid, C rectangular pyramid, D triangular prism.

Here are the solutions to your questions: 1.1 The total distance around the 2D shape The correct option is B. Step 1: Understand the definitions of the given terms. • Volume is the amount of space a 3D object occupies. • Perimeter is the total distance around the boundary of a 2D shape. • Area is the amount of surface a 2D shape covers. • Kilometer is a unit of length. Step 2: Match the definition to the question. The "total distance around the 2D shape" is the definition of perimeter. The answer is B. Perimeter. 1.2 The name of the 3D object below The correct option is C. Step 1: Analyze the shape of the 3D object. The object has a base that is a rectangle and four triangular faces that meet at a single point (apex). Step 2: Identify the type of 3D object. A 3D object with a polygonal base and triangular faces meeting at an apex is called a pyramid. Since the base is a rectangle, it is a rectangular pyramid. The answer is C. Rectangular pyramid.
