Question

HELP ASAP! I REALLY NEED IT!

Answer 1

`46 (7)/(8) \: cubic \: feet`

Explanation:

`\boxed{volume \: of \: prism = base \: area \: * height}`

Base area= length ×width

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

Width

= 7½

`= (7(2))/(2) + (1)/(2)`

`= (14)/(2) + (1)/(2)`

`= (15)/(2) ft`

Height

= 1¼

`= (4)/(4) + (1)/(4)`

`= (5)/(4) ft`

Volume of prism

`= 5 * (15)/(2) * (5)/(4)`

`= (375)/(8)`

`= 46 (7)/(8) \: ft {}^(3)`
