Answer:
5/8
Step-by-step explanation:
The sectors are labeled 1,2,3,4,5,6,7,8
Numbers less than 4: 1,2,3
Multiples of 4: 4,8
We are looking for 1,2,3,4,8 = 5 choices
P (1,2,3,4,8) = Number of choices/ total
= 5/8
231
first of all it must be a cuboid bcoz a cube's edge is same i.e length =breadth= height.
now volume of cuboid =lbh
11/2×21/2×4
=231
ans....
B. x > 4
12 < 8 + x
12-8 < 8-8 +x
12-8 < x
4 <x
x > 4
