It has 12 straight edges
It has 12 of them.
How many straight edges does a cube have? It has 12 straight edges. It can be solved by drawing it out, or using Euler's Theorem. F+V=E+2 The number of faces is 6, and the number of vertices is 8, so 6+8=14. 14-2=12. So there are 12 straight edges in a cube.
