1. Consider the surface area of the pyramid shown. (a) Write the formula for the area of the base. What is the area of the base? Show your work.(b) Write the formula for the area of one side. What is the area of the side? Show your work.(c) Use part (a) and part (b) to find the total surface area. Show your work.
Accepted Solution
A:
The formula for the area of the base is side squared so it would be A= 3 cm x 4 cm which equals 12 cm so the area for the base is 12 cm.
The formula for the area of one side of the pyramid would be 1/2 x b x h. So you would multiply 1/2 x 3 x 2.24 which equals 3.36. Since there are 4 side you would need to multiply 3.36 x 4 which equals 13.44.
So now all you need to do is add the base area and the side area, 13.44 and 12 cm, to get 25.44.
It's all pretty simple once you think about it. Hope you pass!
