Question

The lengths of the sides of the base of a right square pyramid are 2 m, and the slant height of the pyramid is 9 m. If the sides of the base and the slant height are each multiplied by 4, by what factor is the surface area multiplied? A. 8 B. 16 C. 18 D. 36

Answer 1

Answer:

height h = 9 m

slant height s = 9.0553851381374 m

side length a = 2 m

lateral edge length e = 9.1104335791443 m

1/2 side length r = 1 m

volume V = 12 m3

lateral surface area L = 36.22154055255 m2

base surface area B = 4 m2

total surface area A = 40.22154055255 m2

Explanation:

Answer 2

Answer: B.) 16

Step-by-step explanation: If both the length of the base and the slant height of a right sqaure pyramid are multiplied by a factor of 'K' the Surface area of the pyramid is multiplied by a factor of 'K' ²

4² = 16

Im sorry im many months late but hopefully this can help someone else.
