Calculate 31651

Calculate the surface of a regular 5-sided prism with a base area of 60 dm2 if the length of the edge of the lower base is four dm. The height of the prism is 1.3 m.

Correct answer:

S =  380 dm2

Step-by-step explanation:

S1=60 dm2 a=4 dm h=1.3 m dm=1.3 10  dm=13 dm n=5  S2=a n h=4 5 13=260 dm2  S=2 S1+S2=2 60+260=380 dm2
