i need this answer rn A triangular pyramid has a base shaped like an equilateral triangle. The legs of the equilateral triangle are all 5 inches long, and the height of the equilateral triangle is 4.3 inches. The pyramid's slant height is 5 inches. What is its surface area?

48.25 in^2.

Step-by-step explanation:

Surface area of the base

= 1/2 & base * height

= 1/2 * 4.3 * 5

= 10.75 in^2.

Area of each triangular side

= 1/2 * 5 * 5

= 12.5 in^2.

So total surface area

= 10.75 + 3 * 12.5

=  48.25 in^2.

the answer is b i just did that
