Find the surface area of a square pyramid given that it’s base area is 196 square inches and the height of each of its triangular faces is 16 inches

Step-by-step explanation:

Since it's a square, and it's given that the area of the square is 196 inches, each side of the square is equal. Area = length * width and in that case, one side of the square is 14 because = 14.

The area of a triangle is 1/2(bh) and the height is already given (16). So, substitute the lengths of one side of a square into the equation.

Area of a triangle = 1/2 (14*16) which equals 112 inches square.

There are 4 triangles which makes 112 * 2 = 448.

448 + the area of the square (196) =
