question 21 of 25
which sentence best describes these two cell models?
a
b
a. they have the same volume, but model b has more surface area.
b. they have the same surface area, but model a has more volume.
c. they have the same volume, but model a has more surface area.
d. they have the same surface area, but model b has more volume.

Explanation:

Step1: Analyze volume

Volume is the amount of space occupied. Model B is made by dividing model A into smaller - cubes without adding or removing any material, so volumes are equal.

Step2: Analyze surface - area

Surface - area is the total area of the exposed surfaces. When model A is divided into smaller cubes (model B), more surfaces are exposed. So model B has a larger surface - area.

Answer:

A. They have the same volume, but model B has more surface area.
