Question

What is the surface area of the regular pyramid below

Answer 1

`</p><p>S=14*14+4((14)/(2)*18) \\</p><p>S=196+4(7*18) \\</p><p>S=196+4*126 \\</p><p>S=196+504 \\</p><p>S=\boxed{700}</p><p>`

Answer 2

B.
`700\text{ inches}^2`.

Explanation:

We have been given an image of a pyramid. We are asked to find the total surface area of the given pyramid.

`\text{Surface area of pyramid}=A+(1)/(2)*ps`, where,

A = Area of base of pyramid.

p = Perimeter of base,

s = Slant height,

Upon substituting our given values, we will get:

`\text{Surface area of pyramid}=14^2+(1)/(2)*4*14*18`

`\text{Surface area of pyramid}=196+2*14*18`

`\text{Surface area of pyramid}=196+504`

`\text{Surface area of pyramid}=700`

Therefore, the total surface area of given pyramid is 700 square inches and option B is the correct choice.
