Answer:

1. surface area

2. geometry net

3. rectangular prism

4. cylinder

5. square units

Step-by-step explanation:

1. Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

2.The area is always expressed in square units. The standard units that are generally used for measuring area are square centimeter and square meter.

3.A flat pattern that you can fold to form a solid figure is called a net. Example : Tetrapak bottles, cartons, etc

4.A rectangular prism is a polyhedron with two congruent and parallel bases. It is also a cuboid. It has six faces, and all the faces are in a rectangle shape and have twelve edges. Because of its cross-section along the length, it is said to be a prism.

5.The sum of the areas of the two circular bases and rectangular lateral area is the surface area of the. 5. To measure surface area, we use. units
