Question

A suitcase is a rectangular prism whose dimensions are 1 &1/4 feet by 1 & 3/4 feet by 1 & 1/4 feet.Find the volume of the suitcase.

ANSWER THIS PLEAAAAAAASSSSS

Answer 1

1 1/4=5/4
1 3/4=7/4
v=5/4*5/4*7/4=175/64feet^3

Answer 2

`V=2(47)/(64)ft^(3)`

Explanation:

The volume of a rectangular prism is defined as

`V=l * w * h`

Where
`l` is length,
`w` is width and
`h` is height.

In this case, the dimensions are

`1(1)/(4)ft`,
`1(3)/(4)ft` and
`1(1)/(4)ft`.

First, we need to transform all mixed numbers into fractions.

`1(1)/(4)ft =(5)/(4)ft`

`1(3)/(4)ft=(7)/(4)ft`

So, using the formula

`V=l * w * h=(5)/(4)ft * (7)/(4)ft * (5)/(4)ft=(175)/(64)ft^(3)\\V=2(47)/(64)ft^(3)`

Therefore, the volume of the suitcase is
`V=2(47)/(64)ft^(3)`
