The diagram below shows the design for a piece of furniture made of three cubes join together? What is the total surface area of the piece of furniture a 24 ft.² B 28 ft.² C 56 ft.² D 72 ft.²

Answer 1

To find the total surface area of the piece of furniture, we need to find the surface area of each cube and then add them together.

Each cube has a surface area of 6 sides, and since there are three cubes, the total surface area would be:

6 (surface area of one cube) * 3 (number of cubes) = 18 ft²

Therefore, the total surface area of the piece of furniture is 18 ft².

Therefore, the correct answer is A) 18 ft².
