Answer:

10 \frac{1}{2}

Step-by-step explanation:

to multiply, convert each fraction into an improper fraction. you do that by multiplying the denominator by the whole number and adding the numerator. so 3 \frac{3}{4} will be \frac{15}{4} and 2 \frac{4}{5} will be \frac{14}{5}. now you multiply the numerator by the numerator and the denominator by the denominator. your fraction will be \frac{210}{20}. to simplify, you divide 210 by 20 and you will get 10 \frac{1}{2} :)

Answer:

The dimensions of the prism are 1, 2/3, and 5/3.

Multiplying all of these numbers, we see that the final volume of the prism is 10/9 units, which is also equal to 1 1/9, so the first choice (the one to the left) is correct.

Let me know if this helps!
