What is the surface area?
7ft tall 4ft depth 4ft long
The surface area of an object refers to the total area of all its surfaces.
To calculate the surface area of a rectangular prism with dimensions 7ft tall, 4ft depth, and 4ft long, we need to find the area of each of its six sides.
The formula for calculating the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Where:
l = Length
w = Width
h = Height
Using the given dimensions:
Length = 4ft
Width = 4ft
Height = 7ft
Surface Area = 2(4)(4) + 2(4)(7) + 2(4)(7)
Surface Area = 32 + 56 + 56
Surface Area = 144ft²
Therefore, the surface area of the rectangular prism is 144 square feet.
