Answer:
26(1)/(4)\text{ inches}^3

Explanation:

Given : In a rectangular prism , length =
3(1)/(2)\text{ inches}


=(3(2)+1)/(2)=(7)/(2)\text{ inches}

width = 5 inches

height=
1(1)/(2)\text{ inches}=(3)/(2)\text{ inches}

Now, the volume of the prism will be :-


V= l* w* h\\\\=(7)/(2)*5*(3)/(2 )\text{ inches}^3\\\\=(105)/(4)\text{ inches}^3\\\\=26(1)/(4)\text{ inches}^3

Hence, the volume of the prism
=26(1)/(4)\text{ inches}^3

Answer:

The volume of the prism in the decimal form is 26.25 inches³ and
26 (1)/(4)\ inches^(3)

Explanation:

Formula

Volume of a rectangular prism = Length × Breadth × Height

As given

A rectangular prism has a length of
3 (1)/(2)inches, a width of 5 inches, and a height of
1 (1)/(2) inches.

i.e

A rectangular prism has a length of
(7)/(2)inches, a width of 5 inches, and a height of
(3)/(2) inches.


Volume\ of\ a\ rectangular\ prism = (7)/(2)* 5* (3)/(2)


Volume\ of\ a\ rectangular\ prism = (7* 5** 3)/(2* 2)


Volume\ of\ a\ rectangular\ prism = (105)/(4)

In mixed number


Volume\ of\ a\ rectangular\ prism =26 (1)/(4)\ inches^(3)

In decimal form


Volume\ of\ a\ rectangular\ prism = 26.25\ inches^(3)

Therefore the volume of the prism in the decimal form is 26.25 inches³ and
26 (1)/(4)\ inches^(3)
