Question

Find the volume of each prism.

Answer 1

`\large\boxed{V=618(3)/(4)\ yd^3}`

Explanation:

The formula of a volume of a rectangular prism:

`V=lwh`

l - length

w - width

h - height

We have:

`l=5\ yd,\ w=10\ yd,\ h=12(3)/(8)\ yd=(12\cdot8+3)/(8)\ yd=(99)/(8)\ yd`

Substitute:

`V=5\cdot10\cdot(99)/(8)=5\cdot5\cdot(99)/(4)=(2475)/(4)=618(3)/(4)`
