Let's calculate the surface area of a rectangular prism. The formula for the surface area ($SA$) of a rectangular prism with length ($l$), width ($w$), and height ($h$) is: $$SA = 2lw + 2lh + 2wh$$ Step 1: Identify the dimensions. Let's assume a rectangular prism has the following dimensions: Length ($l$) = $5$ cm Width ($w$) = $3$ cm Height ($h$) = $2$ cm Step 2: Substitute the values into the formula. $$SA = 2(5 \text{ cm})(3 \text{ cm}) + 2(5 \text{ cm})(2 \text{ cm}) + 2(3 \text{ cm})(2 \text{ cm})$$ Step 3: Perform the multiplications for each term. $$SA = 2(15 \text{ cm}^2) + 2(10 \text{ cm}^2) + 2(6 \text{ cm}^2)$$ $$SA = 30 \text{ cm}^2 + 20 \text{ cm}^2 + 12 \text{ cm}^2$$ Step 4: Add the terms together to find the total surface area. $$SA = 62 \text{ cm}^2$$ The surface area of the rectangular prism is $\boxed{\text{62 cm}^2}$. 3 done, 2 left today.
