Complete Question

Which formulas can be used to find the surface area of a regular pyramid

where p is the perimeter of the base, s is the slant height, BA is the base area,

and LA is the lateral area?

Check all that apply.

a) SA = BA + 1/2ps

b) SA = 2BA + 1/2ps

c) SA = BA + LA

d) SA = BA + 2LA

e) SA = 8.LA

a) SA = BA + 1/2ps

d) SA = BA + 2LA

Step-by-step explanation:

When finding the surface area of a regular pyramid it is important to take note of two things

A pyramid has a Base area which is always represented by BA.

a) When a regular pyramid has similar ( side)faces, for examples a regular square pyramid, which has the base of a square, the formula to use is

Surface Area = Base Area + 1/2ps

Where p = Perimeter of the side faces

s = Slant height.

b) When the side faces are not so similar , for example, we are given a triangular based pyramid, the formula we would use is given as:

Surface Area = Base Area + Lateral Area.

Therefore, the formulas we can use to find the Surface Areas or a regular pyramid are:

a) SA = BA + 1/2ps

d) SA = BA + 2LA
