Question

HELP ASAP! I REALLY NEED IT!

Answer 1

Answer:

$46 \frac{7}{8} \: cubic \: feet$

Step-by-step explanation:

$\boxed{volume \: of \: prism = base \: area \: \times height}$

Base area= length ×width

Let's convert all the mixed numbers into improper fraction for easier calculation.

Width

= 7½

$= \frac{7(2)}{2} + \frac{1}{2}$

$= \frac{14}{2} + \frac{1}{2}$

$= \frac{15}{2} ft$

Height

= 1¼

$= \frac{4}{4} + \frac{1}{4}$

$= \frac{5}{4} ft$

Volume of prism

$= 5 \times \frac{15}{2} \times \frac{5}{4}$

$= \frac{375}{8}$

$= 46 \frac{7}{8} \: ft {}^{3}$
