Question

which strategy could you use to find the actual number of sticky notes it will take to cover the cabinet, excluding the bottom? think about each strategy in terms of sticky notes. a find the area of each rectangular side of the cabinet, excluding the bottom, and add them together. b add the length, width, and height of the file cabinet to get the total number of sticky notes needed. c find the area of one side of the cabinet, then multiply by five because there are five sides. d find the perimeter of each rectangular side, excluding rectangular bottom, then add them together.

Explanation:

To find the number of sticky - notes to cover the cabinet (excluding the bottom), we need to find the surface area to be covered. Surface area is calculated by finding the area of each face and adding them. Option A correctly suggests finding the area of each rectangular side of the cabinet (excluding the bottom) and adding them together. Option B is incorrect as adding length, width, and height gives a linear measurement, not an area. Option C is incorrect because the sides of a cabinet are not all the same area, so multiplying the area of one side by five is wrong. Option D is incorrect as perimeter measures the length around a shape, not the area to be covered.

Answer:

A. Find the area of each rectangular side of the cabinet, excluding the bottom, and add them together.
