Question

lesson 8: surface area and volume surface area and volume the surface area of a figure is ______ a. expressed in cubic units b. the sum of the areas on all the sides c. found by multiplying the areas on the top, bottom, and one side d. the amount of space it occupies

Explanation:

• Option a: Cubic units are for volume, not surface area (surface area uses square units), so a is wrong.
• Option b: By definition, surface area is the sum of the areas of all the faces (sides) of a 3D figure, so this matches.
• Option c: Surface area is a sum, not a product of selected areas, so c is wrong.
• Option d: The amount of space occupied is volume, not surface area, so d is wrong.

Answer:

b. the sum of the areas on all the sides
