Total number of edges of a cuboid is (a) 4 (b) 6 (c) 8 (d) 12

A polyhedron with 8 faces and 12 vertices has .......... edges.

If x % of 75 is 12, then x= (a) 8 (b) 10 (c) 12 (d) 16

Total number of faces of a cuboid is (a) 4 (b) 6 (c) 8 (d) 12

Number of vertices of a cuboid is (a) 4 (b) 6 (c) 8 (d) 12

If 2 is a root of the equation x^2+b x+12=0 and the equation x^2+b x+q=0 has equal roots, then q= (a) 8 (b) -8 (c) 16 (d) -16

If 2 is a root of the equation x^2+b x+12=0 and the equation x^2+b x+q=0 has equal roots, then q= (a) 8 (b) -8 (c) 16 (d) -16

Total number of edges of a cuboid is 4 (b) 6 (c) 8( d )12
