To find the surface area of a rectangular pyramid, we need to calculate the area of each face and then sum them all together.
The rectangular pyramid has 5 faces:
1 base (a rectangle) and 4 triangular faces.
Let's say the dimensions of the base rectangle are length (L) and width (W), and the height of the pyramid is H.
The area of the base rectangle = L * W
The area of each triangular face = 1/2 * base * height of the triangle
Total surface area = area of base rectangle + 4 * area of triangular faces
Surface area = LW + 4(1/2 * LW)
= LW + 2 LW
= 3 LW
Therefore, the surface area of a rectangular pyramid is 3 times the area of the base rectangle.
