The length of the base of a rectangular prism is 9
Tatiana [17]

Answer:

The volume of the prism is <u>320 15/16 inches³</u>.

Step-by-step explanation:

Given:

The length of the base of a rectangular prism is 9 7/8.

The width of the prism is 8 1/8.

And the height is 4 inches.

Now, to find the volume of the prism.

(Length) <em> l = 9 7/8 = 79/8 inches.</em>

(Width)  <em> w = 8 1/8 = 65/8 inches</em>.

(Height)  <em>h = 4 inches</em>.

So, by putting the formula to get the volume:

Volume = w×h×l.

Volume=\frac{65}{8}\times 4\times \frac{79}{8}

Volume=320\frac{15}{16}

<em>Volume = 320 15/16 inches³.</em>

Therefore, the volume of the prism is 320 15/16 inches³.

Kylie drank 35% ofna 400-mL contanier of water.Eugenia drank 45% of a 350 mL container of water.who drank more?Explain how you k
Andrei [34K]
Let Kylie's container (which is 400ml) be 100%. She drank 35%. Proportion:
400ml - 100%
x ml    - 35%
So Kylie drank:
x=(400*35)/100=140 ml of water

Whole Eugenia's container (350ml) is also 100% and she drank 45%.
350ml - 100%
xml     - 45%
Eugenia drank:
x=(350*45)/100=157,5ml of water

Thus, Eugenia drank (157,5-140)=17,5 ml more than Kylie
