Question

marcia makes a cut through a block of frozen spinach, as shown. what are the dimensions of the exposed cross - section?
options:
a. 6 cm×8 cm
b. 16 cm×16 cm
c. 8 cm×10 cm
d. 6 cm×10 cm

Explanation:

Step1: Analyze the cross - section

The block of frozen spinach is a rectangular prism. When a cut is made parallel to the face with dimensions 6 cm and 8 cm (assuming the cut is such that the cross - section is a rectangle with sides equal to the height and the side length of the base), the exposed cross - section will have the same dimensions as the face that is parallel to the cut. The two dimensions of the relevant face are 6 cm and 8 cm.

Step2: Match with options

Looking at the options, option A has dimensions 6 cm×8 cm which matches our analysis. Options B (16 cm×16 cm) is incorrect as there are no 16 cm dimensions given. Option C (8 cm×10 cm) and option D (6 cm×10 cm) are incorrect because the cross - section is not parallel to the faces with 10 cm as one of the sides in this case.

Answer:

A. 6 cm×8 cm
