So each dimention is 32 by 8 by 10
so the surface area=2 times(8 times 10)+(2 times (32 times 10))+(2 times (8 times 32))=2 times 80+2 times 320+2 times 256=1312
if halved
just divide each by 2
(2 times 4 times 5)+(2 times 16 times 5)+(2 times 4 times 16)=(2 times 20)+(2 times 80)+(2 times 64)=40+160+128=328
the new surface area is 328 mm^2
3.14 x 9^2 x 14/3 = 1186.92
4/3 x 3.14 x 9^3 = 1526.04
1186.92 + 1526.04 = 2712.96 = 2713 cubic inches
Answer:
To the right
Step-by-step explanation:
The negatives on a number line are on the left side and the positives on the right.

Note:If you have any question about it you can ask.
Answer:
Step-by-step explanation:
First, a regular octahedron has a minimum of six vertices and twelve edges.
What is the probability that 2 vertices (randomly chosen) will be the endpoints of an edge of the octahedron?
NOTE:
The edges are the lines that join the points together, to form the shape.
The points are the vertices; each point being called a vertex.
Hence, the probability that 2 randomly chosen vertices will be the endpoints of an edge (a particular edge) of the octahedron is
6/12 = 1/2 = 0.5
