Find the surface area of a rectangular pyramid with these measurements: l = 15 m, w = 12 m, and h = 10 m. Express your answer as a decimal rounded to the nearest hundredth.(1 point)
m2
To find the surface area of a rectangular pyramid, we need to find the area of each face and then add them together.
The rectangular pyramid has 4 triangular faces and 1 rectangular base.
To find the area of each triangular face, we can use the formula A = (1/2) * base * height.
For the rectangular base, we can use the formula A = length * width.
A = (1/2) * 15m * 10m = 75m^2
A = (1/2) * 15m * 10m = 75m^2
A = (1/2) * 12m * 10m = 60m^2
A = (1/2) * 12m * 10m = 60m^2
A = 15m * 12m = 180m^2
Now we can add all the areas together to find the surface area:
75m^2 + 75m^2 + 60m^2 + 60m^2 + 180m^2 = 450m^2
Therefore, the surface area of the rectangular pyramid is 450 square meters.
