201110 An earthquake measuring 4.8 on the Richter scale occurred in Anqing. In order to support the disaster area, a tarpaulin factory produced a number of mobile tents for building roofs.
The areas of the two inclined planes at the top of the tent are:
2×4.5 1.52+0.652
=9× 1.64≈ 14.8
The area around the tent is:
2×3×2+4.5×2×2+3×0.65
= 12+ 18+ 1.95
=32
It takes at least 32+ 14.8=47 square meters to make such a tent.
