What is the surface area of a rectangular prism that is 24in 36in 54in

Answer 1

To find the surface area of a rectangular prism, you need to calculate the area of each of its six sides and then add them together.

For a rectangular prism with dimensions of 24in, 36in, and 54in, the surface area can be calculated as follows:

1. Top and bottom faces:
Area = length x width
Area = 36in x 24in = 864 in²
(There are two faces, so total area = 864 in² x 2 = 1728 in²)

2. Front and back faces:
Area = length x height
Area = 54in x 24in = 1296 in²
(There are two faces, so total area = 1296 in² x 2 = 2592 in²)

3. Side faces:
Area = width x height
Area = 36in x 54in = 1944 in²
(There are two faces, so total area = 1944 in² x 2 = 3888 in²)

Now, add the total areas of all six sides:
1728 in² (top and bottom) + 2592 in² (front and back) + 3888 in² (sides) = 8208 in²

Therefore, the surface area of a rectangular prism with dimensions 24in, 36in, and 54in is 8208 square inches.
