To calculate the surface area of a rectangular pyramid, you need to add the area of the base to twice the area of one of the triangular faces.
Given that the surface area is 278 yd^2 and the base is a rectangle, let's assume the area of the base is B and the area of each triangular face is T.
So we have:
SA = B + 2T
Since the pyramid is rectangular and we know the surface area and the area of the base, we can set up the equation as follows:
278 = B + 2T
Now, to find B, you can subtract twice the area of the triangle from the total surface area:
2T = 278 - B
2T = 278 - B
At this point, without knowing the specific dimensions of the pyramid, we cannot determine the individual values of B and T to calculate the surface area. The surface area of the rectangular pyramid would depend on the actual dimensions of the base and the triangular faces.
4. Calculate the surface area of the rectangular pyramid below.
