Exploring Surface Area of Pyramids

What shape can the base of a pyramid be?

• Hexagon

• Square or Rectangle

• Circle

• Triangle

How many lateral sides does a pyramid have?

• 4

• 2

• 6

• 8

What is the area of the base for a pyramid with a 30 by 30 square base?

• 900

• 600

• 1200

• 1500

How do you calculate the total surface area of a pyramid?

• Sum of the base area

• Sum of the lateral sides area

• Base area plus the lateral sides area

• Base area multiplied by the lateral sides area

What is the area of one triangular side of a pyramid with a slant height of 40 and a base of 30?

• 300

• 600

• 1200

• 2400

For a pyramid with a rectangular base of 9 by 6, how many sets of equal triangles are there?

• 1

• 2

• 3

• 4

What is the area of the base for a pyramid with a 9 by 6 rectangular base?

• 74

• 54

• 64

• 84

What is the total surface area of a pyramid with a rectangular base of 9 by 6, and triangles with heights of 12.8 and 13.22?

• 248.5

• 3300

• 1200

• 900

Why do we divide by 2 when calculating the area of a triangle?

• Because it has two sides

• To find the midpoint

• Because it's a standard formula

• To convert it into a rectangle

What realization might you come to when calculating the area of the lateral sides of a pyramid?

• You only need to multiply the base by the height for both triangles

• Dividing by 2 is unnecessary

• Adding the areas of all sides gives the total surface area

• Multiplying base by height gives the total area
