Question

Simpson has a rectangular fish aquarium that measures 31 inches long, 13 inches wide, and is 28 inches deep. If Simpson wanted to put a protective covering on the four glass walls of the aquarium, how much covering does he need?

Answer 1

The dimensions of the rectangular fish aquarium are:

length = 31 inches, width = 13 inches and depth = 28 inches

If Simpson covers all the four glass walls of the aquarium.

We have to determine the covering he needs.

So, Covering required for four walls of the aquarium

=
`2(lh+bh)`

=
`2( (31 * 28)+ (13 * 28))`

=
`2( (868)+ (364))`

=
`2 * 1232`

= 2464 square inches

So, Simpson needs 2464 square inches of covering to cover all the four glass walls of the aquarium.
