Step-by-step explanation:
What we can do is use the formula to find volume:
If we use this, by counting, we can see that the length is 6 units. Adding onto that, we can also see that the width is 3 units. Finally, for the height, we can see that it is 4 units.
If we use our handy formula, we get 6×3×4 which gives us 72 units!

Interest rate for one year is rate percent amount of original investment. The amount invested by Mrs. Ming in the account paying 6% was $680
<h3>How to calculate interest after 1 year if the rate of interest is R% annually?</h3>Suppose that annually there is interest rate of R%. The amount initially invested is P, then for 1 year, it doesn't matter if its simple or compounding annually, the interest is same (it doesn't remain same if compounding isn't annually or if the time is > 1 year)
The interest for 1 year will be
Let we have the initial amount spent in account paying 8% interest rate as $x
Let for 6% interest paying account, initial amount was $y
Then, by the given data, we have:
and
Thus, we got a system of linear equations as :
From equation 1, getting value of x in terms of y, we get:
Substituting this value in second equation, we get:
Putting this value of y in the equation we got for x,
Thus, amount invested by Mrs Ming in account paying 8% interest rate as $x = $820
and for 6% interest paying account, initial amount was $y = $680
Thus,
The amount invested by Mrs. Ming in the account paying 6% was $680

We know that a triangle has 3 sides right?
Well, if the perimeter is 39 and there are 3 sides you would divide 39 by the 3 sides
39/3=13
Therefore, one side of the triangle would equal 13
