Perimeter, Area, Volume, and Surface Area For problems 1 – 4, match each question to its answer. 1. What is perimeter? A. The area of all the surfaces of a 3-D shape. 2. What is area? B. The number of cubes that fit inside a shape. 3. What is volume? C. The length around a shape. 4. What is surface area? D. The number of squares inside a shape. Two-dimensional doesn’t have volume but has area only. Example, Volume of Circle cannot be found, though Volume of the sphere can be. It is so because a sphere is a three-dimensional shape.
