The maximum number of supply boxes she can pack in the crate is 300, if supply box is 1.5 feet tall, 1 foot wide, and 2 feet deep. The crate is 9 feet high, 10 feet wide, and 10 feet deep.
Step-by-step explanation:
The given is,
Dimensions of supply box - 1.5 feet tall, 1 foot wide, and 2 feet deep
Dimensions of crate - 9 feet high, 10 feet wide, and 10 feet deep
Step:1
Volume of supply box,
.............................(1)
Where, w - Width of box
h - Height of box
l - Length of box
From the given,
h = 1.5 feet
w = 1 foot
l = 2 feet
Equation (1) becomes,
= 3 cubic feet
Step:2
Volume of crate,
.............................(1)
Where, w - Width of box
h - Height of box
l - Length of box
From the given,
h = 9 feet
w = 10 foot
l = 10 feet
Equation (1) becomes,
= 900 cubic feet
Step:3
No. of boxes can pack in the crate,
=
=
= 300 supply boxes
Result:
The maximum number of supply boxes she can pack in the crate is 300, if supply box is 1.5 feet tall, 1 foot wide, and 2 feet deep. The crate is 9 feet high, 10 feet wide, and 10 feet deep.
A the other ones really don’t make sense
Answer:

Step-by-step explanation:
This is the number of combinations of 4 cards from 9 cards:
= 9C4
= 9! / 4! 5!.
A quick way of calculating this is
9*8*7*6
----------- = 9*2*7 = 126 combinations.
