Question

I need help please give me an answer for this.

Answer 1

surface area of the net pyramid is 125 in²

Step-by-step explanation:

Surface area of a net pyamid is calculated as:

`S\mathrm{}A\text{ = area of base + }(1)/(2)perimeter\text{ of base }* slant\text{ height}`

side of the base = 5 in

Area of the base = area of square

Area of the base = (side of the base)² = 5²

Area of base = 25 in²

Perimeter of base = perimeter of square

Perimeter of base = 4(side of the base) = 4(5)

Perimeter of base = 20 in

slant height = 10 in

Inserting the values into the formula for surface area:

`\begin{gathered} S.A\text{ = }25\text{ + }(1)/(2)(20)(10) \\ S.A\text{ = }25\text{ + 100} \\ S\mathrm{}A\text{ = 125 in}^(2) \end{gathered}`
