Pyramid Surface Area and Geometry

This video tutorial explains how to calculate the surface area of a pyramid. It begins by introducing the concept of surface area and then details the process of calculating the area of the pyramid's base, which is a square, and the area of its triangular sides. Finally, it demonstrates how to sum these areas to find the total surface area of the pyramid.

What is the first step in finding the surface area of a pyramid?

• Calculate the volume of the pyramid

• Add the areas of all the faces of the pyramid

• Find the height of the pyramid

• Determine the perimeter of the base

What shape is the base of the given pyramid?

• Square

• Circle

• Rectangle

• Triangle

How do you calculate the area of a square?

• Side squared

• Base times height

• 1/2 base times height

• Length times width

What is the area of the base of the pyramid if each side is 7 ft?

• 14 square ft

• 49 square ft

• 35 square ft

• 70 square ft

How many triangular sides does the pyramid have?

• Five

• Three

• Four

• Two

What is the formula for the area of a triangle?

• Side squared

• Length times width

• Base times height

• 1/2 base times height

What is the area of each triangular side if the base is 7 ft and the height is 10 ft?

• 70 square ft

• 49 square ft

• 35 square ft

• 140 square ft

What is the total area of all four triangular sides of the pyramid?

• 140 square ft

• 70 square ft

• 280 square ft

• 35 square ft

What is the final step in finding the total surface area of the pyramid?

• Multiply the base area by the height

• Add the area of the base to the area of the sides

• Subtract the base area from the side area

• Divide the total area by the number of sides

What is the total surface area of the pyramid?

• 189 square ft

• 140 square ft

• 49 square ft

• 210 square ft
