Find the Lateral area and surface area of the regular pyramid.
Answer to Problem 1CYU
L =
S =
Explanation of Solution
Given:
Formula Used: The Lateral area L of a regular Pyramid is
The Surface area S of a regular Pyramid is
Calculation:
The pyramid has a base that is square whose length is 16 cm and the slant height is 12 cm.
Perimeter of the base = P = 4(length of each side) = 4(16) = 64 cm.
The Lateral area =
Area of the base = B = (length of each side )(length of each side)=
So, the surface area of the pyramid :
Hence ,
L =
S =
