Which statement is true about every rectangular pyramid? Each lateral face has an area less than the area of the base. At least two of the lateral faces are congruent. Each lateral face has the same height. At least one of the faces has a whole number base or height.

B is correct

Step-by-step explanation:

597

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
