Understanding Surface Area of a Rectangular Pyramid

The video tutorial explains how to calculate the surface area of a rectangular pyramid. It begins by calculating the area of the rectangular base, followed by the areas of the triangular sides, which have different base lengths. The tutorial emphasizes the importance of recognizing the different triangle bases and concludes by summing all the areas to find the total surface area, which is 278 cm².

What is the formula used to calculate the area of the rectangle at the base of the pyramid?

• Length x Height

• 2 x (Length + Width)

• Length x Width

• Length + Width
