we have 630 one-inch unit cubes and we want to completely fill the rectangular box (unknown dimensions).
If all the cubes are fitted tightly inside rectangular box without living any space, then box volume would be equal to cubes volume.
There are 630 one-inch unit cubes, so volume of cubes = 630 cubic inches.
Now the volume of rectangular box would also be 630 cubic inches.
We know the formula for volume of rectangular box = length ×
width × height.
So we need to find any three positive integers whose product is 630.
Out of all given choices, only option A satisfies the condition of factors of 630.
Hence, option A i.e. (7 in x 9 in x 10 in) is the final answer.

Step-by-step explanation:
Pls give brainliest!! Have a nice day!!
100 cm= 1 meter 1,000 cm=meter
——————-
750 mm = 0.75 m
45 cm = 0.45 m
2.3 m
——————
Add and you should get 3.5. The tinsel is 3.5 meters long.
Answer:
(a)
The quantity of element that are still contained in the stolen rock
is 37.1627g
(b)
this rock can be used by the superhero's nemesis to render the superhero powerless is 567 years
Step-by-step explanation:
We are given
original quantity =250g
half life time =200 years
so, we can use formula
where
Po is initial quantity
h is half life time
t is time in years
so, we can plug h=200 and Po=250
and we get
(a)
we can plug t=550
and then we can find P(t)
we get
(b)
we can set P(t)=35
and then we can solve for t
we can take ln on both sides
years
Empirical probability is computed by running an experiment multiple times (in this case, asking the same question to many people), and then computing the ratio
In this case, 236 people over 991 said that they checked the portfolio daily, so the empirical probability is
Which you can round as 0.238, i.e. 23.8%.
