the length of one side of the base of a square pyramid is 15 cm. the height of each face is 40 cm. what is the surface area of the pyramid?

B. 1,425 square centimeters

Step-by-step explanation:

Area of the square pyramid = b² + 2bs

Where,

b = length of square base = 15 cm

s = slant height of each face = 40 cm

Surface area of the pyramid = 15² + 2(15)(40)

= 225 + 1,200

Surface area = 1,425 cm²

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

hi there! my name is zalgo and i am here to you out today. the answer is pretty simple (in a way). this equation equals to 25.2!

i hope this answer !
