Surface Area of Square Pyramids

This video tutorial from MooMooMath and Science explains how to find the surface area of a square pyramid using two different methods. The first method involves calculating the base area and adding the areas of four triangles, while the second method uses the perimeter and slant height. Both methods result in the same surface area calculation. The video concludes with a motivational message about kindness.

What is the formula for the surface area of a square pyramid using the first method?

• Base area plus four times the slant height

• Base area plus height times width

• Base area plus perimeter times slant height

• Base area plus four times the area of a triangle

How do you calculate the area of a triangle in the first method?

• Base times height

• One half base times height

• Base plus height

• Base times slant height

What is the base area of the square pyramid if each side of the base is 3 cm?

• 6 cm²

• 9 cm²

• 15 cm²

• 12 cm²

In the first method, why do you multiply the triangle area by four?

• To find the total base area

• Because there are four triangles in the pyramid

• To account for the slant height

• To convert to square units

What is the formula for the surface area of a square pyramid using the second method?

• Base area plus four times the area of a triangle

• Base area plus height times width

• Base area plus four times the slant height

• Base area plus one-half times perimeter times slant height

How do you calculate the perimeter of the base in the second method?

• Multiply the base length by the height

• Add all the side lengths of the base

• Divide the base area by the height

• Subtract the slant height from the base length

What is the slant height used in the second method calculation?

• 6 cm

• 4 cm

• 3 cm

• 5 cm

What is the result of multiplying the perimeter by the slant height in the second method?

• 90

• 120

• 60

• 30

What is the final surface area of the square pyramid using either method?

• 29 cm²

• 39 cm²

• 59 cm²

• 49 cm²

What is the key takeaway message at the end of the video?

• Always double-check your work

• Math is fun

• Kindness multiplies kindness

• Practice makes perfect
