Answer:
cubic feet
Step-by-step explanation:
If these are the width, length and height of a rectangular box (such details were not specified in the question), the volume is calculated by multiplying the three quantities because the volume of a rectangular prism is : width x height x length.
The easiest way to do it when mixed numbers are involved (specially when the denominators of the fractions are "4" like in your case), is to convert them to decimal form and then do the multiplication:
3 1/4 = 3.25
3 3/4 = 3.75
now do the product of the three quantities:
3 x 3.25 x 3.75 = 36.5625 = 36 + 0.5625
now convert 0.5625 into fraction form: 9/16 and you get the final answer (remember to include the cubic form of the units "ft" since each quantity you multiply carries a feet unit:
36 9/16 cubic feet
So we start by combining like terms;
Now we have;
We then subtract 1 from both sides;
Then we divide both sides by 5;
Leaving the final answer to be h = -2
