Answer:
part A : Sides A-E-H-D and B-F-G-C have the same dimensions as a cross section parallel to side A-E-H-D
part B: The length of the side is 3 inches, and the width of the side is 3 inches.
The perimeter can be found using this formula:
perimeter
=
2(length + width)
=
2(3 + 3)
=
2(6)
=
12 inches.
Part C:The dimensions of a cross section that is parallel to side AEHD are the same as those of side A-E-H-D. So the perimeter of a parallel cross section is the same as the perimeter of side A-E-H-D, or 12 inches.
part D: The cross section that passes through the points A, F, G, and D is the rectangle A-F-G-D.
A-F = D-G = 5 inches
A-D = G-F = 3 inches
PART E: F = D-G = 5 inches
AD = G-F = 3 inches
area of rectangle A-F-G-D
=
length × width
=
5 inches × 3 inches
=
15 square inches
