Pyramid surface

Calculate the surface of a 3.5 m high quadrilateral pyramid with a rectangular base with dimensions of 3 m and 1.8 m.

Final Answer:

S =  23.0958 m2

Step-by-step explanation:

h=3.5 m a=3 m b=1.8 m  h1=h2+(b/2)2=3.52+(1.8/2)23.6139 m h2=h2+(a/2)2=3.52+(3/2)23.8079 m  S1=2a h1=23 3.61395.4208 m2 S2=2b h2=21.8 3.80793.4271 m2  S=2 S1+2 S2+a b=2 5.4208+2 3.4271+3 1.8=23.0958 m2
