Question

You are designing a large rectangular fish tank for your tropical fish. The length will be 1 yard 3 inches, the width will be 1.5 feet, and the height will be 20 inches. Find the volume of your fish tank in cubic inches.

Answer 1

One yard is 36 inches, 1.5 feet is 18 inches. 
So the answer is...
   (36+3)*18*20
= 39*18*28
= 702*28
= 19,656

Answer 2

Answer: 14040 cubic inches

Step-by-step explanation:

Given: The length of the rectangular fish tank = 1 yard 3 inches

=36 inches+3 inches=39 inches [Since 1 yard= 36 inches]

The width of the rectangular fish tank= 1.5 feet$=1.5\times12=18\ inches$ [Since 1 foot=12 inches]

The height of the rectangular fish tank=20 inches

Now, the volume of the rectangular fish tank=$length\times\ width\times\ height$

$39\times18\times20=14040\ cubic\ inches$
