If we double the dimension the volume will be increased by 8 times, and the volume will be 1920 cubic m.
<h3>What is the
Volume of
a rectangular prism?</h3>
The Volume of rectangular prism = l×b×h
The volume of a prism,
V = L x B x H
V = 4 x 6 x 10
V = 240
When all the dimensions are doubled, the new volume will become
V1 =2L x 2B x 2H
V1 = 8(4 x 6 x 10)
V1 = 8(240)
V1 = 1920 cubic m
If we double the dimension the volume will be increased by 8 times, and the volume will be 1920 cubic m.

Answer:
9 13
a_. b=_
3 3
Step-by-step explanation:
it's that because you can devid 9 by 3
solution:
I choose 5 women from a pool of 10 in 10C2 ways.
I choose 5 men from a pool of 12 in 12C2 ways.
So total number of ways of choosing in 10C2 x 12C2. Now I need to arrange them in 5 pairs. This is where I have a different solution. The solution says that there are 5! ways to arrange them in pairs.
But I cant seem to understand why? My reasoning is that for first pair position I need to choose 1 man from 5 and 1 woman from 5. So for the first position I have 5 x 5 choices (5 for man and 5 for woman). Similarly for the second position I have 4 x 4 choices and so on. Hence the total ways are 5! x 5!
So I calculate the total ways as 10C2 * 12C2 * 5! * 5!. Can anyone point the flaw in my reasoning for arranging the chosen men and women in pairs.
A and D are the correct answers
