Base diagonal

In a regular 4-sided pyramid, the side edge forms an angle of 55° with the base's diagonal. The length of the side edge is eight meters. Calculate the surface area and volume of the pyramid.

Correct answer:

S =  137.0161 m2
V =  91.9869 m3

Step-by-step explanation:

V=13 S1 h=13 42.1107 6.5532=91.9869 m3
