Calculate the surface area of a right rectangular prism. Each edge length is 15 ft.
To calculate the surface area of a right rectangular prism, we need to find the area of each of its faces and then sum them up.
A right rectangular prism has 6 faces.
Each face is a rectangle, and since all edge lengths are the same, each face has dimensions of 15 ft x 15 ft.
Therefore, the area of each face is 15 ft x 15 ft = 225 square feet.
Since there are 6 faces, the total surface area of the right rectangular prism is 6 x 225 square feet = 1350 square feet.
