A square pyramid with a = 20 mm and b = 96 mm is shown. What is the length of side c? * Hint: you must divide the "b" by two to find the base of the right triangle

Answer: Length of side c = 52 mm

Step-by-step explanation:

Given the following;

a = 20mm

b = 96mm

Find c

Using Pythagoras theorem, where 'c' is the slant height that is, the side of the triangle opposite to the right angle

'c' is the hypotenus

c^2 = a^2 + b^2

b is the base of the right angle

b = 96/2 = 48mm

c^2 = 20^2 + 48^2

c^2 = 400 + 2304

c^2 = 2704

c = sqrt (2704)

c = 52mm

Length of side c = 52mm
