A rectangular prism and its dimensions are shown in the diagram. What is the total surface area of this rectangular prism in square inches?

What is the difference between lateral area and total surface area?

• Total surface area includes 1 base instead of 2 bases like lateral does

• Lateral includes all the faces while total only includes the bases

• Total surface area includes the base(s) and all the faces while lateral does not include the base(s)

• Lateral just includes B, the area of the base while total does not
