By definition, the geometric mean of n numbers is the n-th root of the product of the numbers.
We are given two numbers: 21 and 54.
Their product is 21*54 = 1134
Because we have two numbers, their geometric mean is
√(1134) = 33.675
Answer: 33.675
The surface area of the square pyramid is: 451 cm²
The lateral surface area of the square pyramid = 330 cm²
<h3>What is the Lateral Surface Area and Surface Area of a Square Pyramid?</h3>
Surface area = a² + 2al, where a is the base edge and l is the slant height.
Lateral Surface Area = 2al.
Given the following:
Surface area = a² + 2al = 11² + 2(11)(15)
Surface area = 451 cm²
Lateral Surface Area = 2al = 2(11)(15)
Lateral Surface Area = 330 cm²
