Answers
1,643.2 cm^2 squared
1,001.6 cm^2 squared
102,787.2 cm^2 squared
1,178.8 cm^2 squared
it's 1001.6
The surface area of the rectangular pyramid can be calculated using the formula:
Surface Area = Base Area + (1/2) * Perimeter of Base * Slant Height
First, calculate the base area:
Base Area = length * width = 20 * 18 = 360 cm²
Next, calculate the perimeter of the base:
Perimeter = 2(length + width) = 2(20 + 18) = 76 cm
Now, calculate the surface area using the given slant heights:
Surface Area = 360 + (1/2) * 76 * 16.6 + (1/2) * 76 * 17.2
Surface Area = 360 + 630.8 + 656.8
Surface Area = 360 + 1287.6
Surface Area = 1647.6 cm²
Therefore, the surface area of the rectangular pyramid is 1,647.6 cm². Is this what you mean?
