As stated, the question cannot be answered. The pyramid could be irregular so that its triangular faces have different areas.
If it were a regular pyramid, then with a square base it has four triangular faces whose combined area is
189 - 49 = 140 cm2
So each triangular face has an area of 140/4 = 35 cm2
To calculate the surface area of a regular pyramid, you need to find the area of the base and the area of the triangular faces. The surface area (SA) can be expressed as SA = Base Area + Lateral Area. For a square base, the base area is the side length squared, and the lateral area is found by calculating the area of each triangular face and summing them. If you provide the base side length and the height of the pyramid, I can help calculate the exact surface area.
To find the lateral surface area of a pyramid, calculate the area of each triangular face and sum them up. For a regular pyramid, this can be done using the formula ( \text{Lateral Surface Area} = \frac{1}{2} \times \text{Perimeter of the base} \times \text{Slant height} ). The total surface area is then found by adding the area of the base to the lateral surface area: ( \text{Total Surface Area} = \text{Lateral Surface Area} + \text{Area of the base} ).
To calculate the surface area of a regular pyramid, you need to find the area of the base and the area of the triangular faces. The surface area (SA) is given by the formula: SA = Base Area + Lateral Area. The base area depends on the shape of the base (e.g., square, triangular), while the lateral area is calculated using the slant height and perimeter of the base. Please provide the dimensions and shape of the base for a specific calculation.
surface area is lateral area
A pyramid and a cone are similar in that both are three-dimensional geometric shapes that have a pointed apex and a base. In both shapes, the apex connects to the base through triangular lateral faces; in the case of a pyramid, these faces are flat triangles, while a cone has a curved lateral surface. Additionally, both shapes can be described in terms of volume and surface area formulas, which are derived from their respective base areas and heights.

SA equals pi times the radius squared
To find the lateral surface area of a pyramid, calculate the area of each triangular face and sum them up. For a regular pyramid, this can be done using the formula ( \text{Lateral Surface Area} = \frac{1}{2} \times \text{Perimeter of the base} \times \text{Slant height} ). The total surface area is then found by adding the area of the base to the lateral surface area: ( \text{Total Surface Area} = \text{Lateral Surface Area} + \text{Area of the base} ).
total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
A cone is a common pyramid-like figure where the base is a circle or other closed curve instead of a polygon. A cone has a curved lateral surface instead of several triangular faces, but in terms of volume, a cone and a pyramid are just alike.

Surface area is squared; volume is cubed.
