Question

the surface area of the entire prism is the number of square units needed to cover all faces without gaps and overlaps. first find the area of the faces you can see.

Explanation:

Step1: Assume each small square has area 1 square unit

Let's count the number of small - squares on each face.

Step2: Count squares on face A

If we assume the prism is made up of small unit - squares, and face A has 4 rows and 3 columns of small squares. The area of face A is $4\times3 = 12$ square units.

Step3: Count squares on face B

Face B has 3 rows and 2 columns of small squares. The area of face B is $3\times2=6$ square units.

Step4: Count squares on face C

Face C has 4 rows and 2 columns of small squares. The area of face C is $4\times2 = 8$ square units.

Answer:

A. 12 square units
B. 6 square units
C. 8 square units
