The answer is 864cm squared.

Step-by-step explanation:

In order to find the surface area of a rectangular prism, the surface area of each shape must be added together to find the total surface area of the prism. In order to find the surface area of a rectangle, the formula is SA = length times width. In a rectangular prism, the dimensions of the rectangles are the same, therefore you can take the 8 cm height that is listed on the side of the bottom two rectangles and multiply it by the width listed on the top of the upmost rectangle which is 24 cm. Multiplying 8 by 24 will give 192cm which must be multiplied by 4 because the rectangular prism consists of 4 of the same rectangle. After calculation that number will turn out to be 768cm. The surface area of the squares will also have to be added to that number. The formula for finding the surface area of a square is also width times height, so you can take the 6cm height and 8cm length listed on the leftmost square and multiply them. That calculation will grant an answer of 48cm which must be multiplied by 2 because there are two of the same square in the rectangular prism. That calculation will grant an answer of 96cm. The surface area of the rectangles (768cm) and the surface area of the squares (96cm) must then be added together to grant the final answer of 864cm squared.
