Tent

Pyramid-shaped tent has a base square with a side length of 2 m and a height 1.7 m. How many meters of canvas is nneded to make it if for a waste should be added 10%?

Correct result:

S =  8.6782 m2

Solution:

a=2 m h=1.7 m  h2=h2+(a/2)2=1.72+(2/2)21.9723 m  S1=a h22=2 1.972321.9723 m2  q=10%=1+10100=1.1  S=4 q S1=4 1.1 1.9723=8.6782 m2
