The surface area of a rectangular pyramid is given by the formula:
SA = lw + lh + wh + 1/2pl
Given the measurements:
l = 15 m
w = 12 m
h = 10 m
We can plug these values into the formula:
SA = (15)(12) + (15)(10) + (12)(10) + 1/2(15)(12)
SA = 180 + 150 + 120 + 90
SA = 540 m^2
Therefore, the surface area of the rectangular pyramid is 540 square meters.
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)

The surface area of a square pyramid is given by the formula:
SA = 2s^2 + sl
Where s is the base edge length and sl is the slant height.
Given the measurements:
Base edge length, s = 1.5 cm
Slant height, sl = 4 cm
We can plug these values into the formula:
SA = 2(1.5)^2 + (1.5)(4)
SA = 2(2.25) + 6
SA = 4.5 + 6
SA = 10.5 cm^2
Therefore, the surface area of the square pyramid is 10.5 square centimeters.
SA = 2s^2 + sl
Where s is the base edge length and sl is the slant height.
Given the measurements:
Base edge length, s = 1.5 cm
Slant height, sl = 4 cm
We can plug these values into the formula:
SA = 2(1.5)^2 + (1.5)(4)
SA = 2(2.25) + 6
SA = 4.5 + 6
SA = 10.5 cm^2
Therefore, the surface area of the square pyramid is 10.5 square centimeters.
