A pyramid-shaped tent has a base square with a side length of 2 m and a height of 1.7 m. How many meters of canvas is needed to make it if we should add 10% for waste?

Correct answer:

S =  8.6782 m2

Step-by-step explanation:

a=2 m h=1.7 m  h2=h2+(a/2)2=1.72+(2/2)21.9723 m  S1=2a h2=22 1.97231.9723 m2  q=100%+10%=1+10010=1.1  S=4 q S1=4 1.1 1.9723=8.6782 m2
