1 and 1/3=1+1/3=3/3+1/3=4/3

1 and 5/8=1+5/8=8/8+5/8=13/8

4 and 1/2=4+1/2=8/2+1/2=9/2

multiply them
volume=(4/3) times (13/8) times (9/2)
volume=(4 times 13 times 9)/(3 times 8 times 2)
volume=468/48
volume=39/4
volume=9 and 3/4 cubic feet

Volume (sandbox)= long x wide x tall

long=4 1/2 ft=(4+1/2) ft=(8+1)/2 ft=9/2 ft
wide=1 5/8 ft=(1+5/8)ft= (8+5)/8 ft=13/8 ft
tall=1 1/2 ft= (1+1/2)ft=(2+1)/2 ft=3/2 ft

Volume=9/2 ft * 13/8 ft * 3/2 ft=(9*13*3) / (2*8*2) ft=351/32 ft³

351/32 ft³=(10*32 + 31)/32 ft³=10 + 31/32 ft³=10 31/32 ft³.

Answer:351/32 ft³ or 10 31/32 ft³

How can you decide if finding common multiples or common factors is helpful in solving problems

Answers

Suppose, John arranges stack of Gold and Silver coins in such a way that each stack either contains Gold or contains Silver coins only.

He also tries to arrange them in the least area.

Here, the number of coins in each stack is the common factor of number of Gold and Silver coins.

If we find the highest common factor, then the area occupied by the coins will be least.

Hence, in this situation, we have to find the common factor.

Suppose, George and David are walking along the circular pathway of a park with different speeds.

The problem is to find the time after which they will meet again at the starting point.

Clearly, here the required time is the common multiple of independent time taken by both.

it depends if you like working with big numbers or not. if you are working with large numbers and you want to bring them down you can use factors. multiples are easier to work with when multiplying to cancel out and make your sum easier

Find the difference between 400 and 273

Answers

To find the difference between,

$400$
and
$273$
means what number should we add to 273 to obtain 400.

To find that number, we subtract 273 from 400.

To do that we need to set up the numbers as below to make the calculation easy for us.

$\: \: \: \: \: \: \: \: 10 \n \: \: \: \: 39 \n \: \: \: \: 400 \n ( - 273)/( \: \: \: \: 127)$

We do the subtraction from right to left.

The first digits are 0 and 3. Since 0 is less than 3, we 'borrow' from the next digit.

But sad for us, the next digit to the right is also zero. So we borrow from the from the first non-zero digit which is 4.

Borrowing 1 from 4 makes the hundred digit reduce to 3. Since we are operating in base 10, the 1 we borrow has a value of 10. Adding that 10 to the zero at the immediate right of 4 makes it 10. Now we can borrow one from this "10". That makes it become 9. That is why you are seeing '39' at the top of the '40'. Now our right mist zero has a value of 10(written at the topmost right).

We subtract 3 from 10 now to get 7.

Then 7 from 9 to get 2.

and 2 from 3 to get 1.

Hence

The difference between,
400 and 273 is 127.

The difference between 400 and 273 is 127

The given numbers are,

400 and 273

The difference between 400 and 273 is calculated by subtracting the smaller number from the larger number. So,

400 - 273 = 127.

Now take a creative approach to solve it,

Imagine you have a basket of 400 apples, and a friend takes away 273 apples. How many apples do you have left?

Simply subtract:

400 - 273 = 127.

Or simply

4 0 0

- 2 7 3
