What is the surface area of a square pyramid with a height of 12 mm and a base that measures 10 mm on each side? Round to the nearest tenth if necessary.
The surface area is given by: AS = Ab + Al Where, Ab: base area Al: lateral area We have then: The area of the base is: Ab = (10) * (10) = 100 mm ^ 2 The lateral area is: Al = (4) * (1/2) * (10) * (root ((12) ^ 2 + (5) ^ 2)) Al = 260 mm ^ 2 The surface area is: AS = 100 + 260 AS = 360 mm ^ 2 Answer: The surface area of a square pyramid is: AS = 360 mm ^ 2
