Question

Eduardo has a 32gallon

Answers

GPT 3.5
, rectangular fish tank that he wants to fill with gravel before adding in the water. He decides he wants a layer of gravel that is 2 inches deep.

First, he needs to calculate the volume of gravel he will need. Since the tank is rectangular, the volume can be calculated by multiplying the length, width, and depth of the tank.

The tank's dimensions are:
Length = 36 inches
Width = 12 inches
Depth = 2 inches

Volume = Length x Width x Depth
Volume = 36 x 12 x 2
Volume = 864 cubic inches

Next, he needs to convert the volume into gallons, as the gravel is typically sold in weight measurements in gallons. To do this, he needs to convert cubic inches to gallons.

1 gallon = 231 cubic inches

Gravel volume in gallons = 864 / 231
Gravel volume in gallons = 3.74 gallons

Therefore, Eduardo will need approximately 3.74 gallons of gravel to create a 2-inch layer in his 32-gallon fish tank.
