This rectangular prism is intersected by a plane that contains points D, E, K, and L.
What is the perimeter of the crosection?
Round to the nearest tenth.
The length of diagonal EK is sqrt(5^2 + 4^2) ≈ 6.403m
Hence perimeter = 2*(12 + 6.403) → 36.8 m (to the nearest tenth of a metre)
.
this sounds familiar... almost like a plane hiting a building... or was it two... what if the question stated 3 planes intersected 2 rectangular prisms :0 XD
