Question

The base has area 1764 cm squared and perimeter 168 cm. What is the surface area of the square pyramid?

4116cm squared
4704cm squared
31,038cm squared
2940cm squared

Answer 1

the surface area would be :

A = 4 (1/2 x b x h) + (l x b)

A = 4 ( 1/2 x 42 x 35) + (42 x 42)

A = 4704 cm squared
