Answer:
360in²
Step-by-step explanation:
The base of the rectangular prism is a rectangle. Since we are to find the area of the base of the cabinet, then we just need to get the area of the rectangle.
Area of a rectangle = Length * Width
Given
Length = 9in
Width = 40in
Area of the base = LW
Area of the base = 9 * 40
Area of the base = 360in²
Therefore the area of the base of the cabinet in square inches is 360in²
