Question

The rectangular prisms of 2 1/2ft,4ft and 4 3/4.Find the volume of prism.

Answer 1

Given:

The dimensions of the prism are given as,

`\begin{gathered} l=4ft \\ b=2(1)/(2)=(5)/(2)ft \\ h=4(3)/(4)=(19)/(4)ft \end{gathered}`

The objective is to find the volume of the prism.

Step-by-step explanation:

The general formula to find the volume of the prism is,

`V=l* b* h\text{ . . . . . . (1)}`

To find volume:

On plugging the given values in equation (1),

`\begin{gathered} V=4*(5)/(2)*(19)/(4) \\ =47.5ft^3 \end{gathered}`

Hence, the volume of the prism is 47.5 ft³.
