Answer
Answer:
$3.5$
Explanation:
Step1: Analyze front - back faces
The front - back face area is composed of two rectangles. One is $0.5\times(0.5 + 0.5)=0.5$ square inches and the other is $0.5\times0.5 = 0.25$ square inches. Total for front - back is $2\times(0.5+0.25)=1.5$ square inches.
Step2: Analyze top - bottom faces
The top - bottom face area: The top and bottom are the same. The area of each is $0.5\times(0.5 + 1.0+0.5)=1$ square inches. Total for top - bottom is $2\times1 = 2$ square inches.
Step3: Analyze side faces
The side - face area: There are two side faces with area $0.5\times0.5$ each, total side - face area is $2\times0.5\times0.5 = 0.5$ square inches.
Step4: Calculate total surface area
Add up all areas: $1.5+2 + 0.5=3.5$ square inches.
