Answer: 19 3/8
Step-by-step explanation:
Add all the fractions and minus it from 28 1/2. So, we have to make all the denominators the same.
1) 3 1/4= 3 2/8
2) 1 3/4= 1 6/8
3) 4 1/8= 4 1/8 ( i multiplied the numerator and denominator by 2 to get number 1 and 2)
If the prism's base is a square, and its width is 3 cm long that means its (the base's) length is also 3 cm. Since it is a square and a square's all sides has the same length. So let's find the base's area. To find it we'll multiply the length of its two sides. Since all sides has the same length, which is 3 cm. 3 times 3 gives us the area of the base.

To find the prism's volume, we multiply its base area with its height. Let's call the height with the variable 'h' . h times base area (which is 9) will give us the volume of the prism (which is 144).
Let's build the equation.

To solve for h, let's divide both sides by 9.

So we've found h (height) as 16 cm.

The answer is : d. 16
