Question

Kianna's aquarium is "box-shaped" with dimensions of 4 ft by 1 ft by 8 in. What is the water capacity of her aquarium in gallons? Consider that 1 ft³ of liquid corresponds to 7.5 gallons of the liquid.

Answer 1

Length= 4ft

Width= 1ft

Depth= 8in

Convert the depth in inches to depth in feet: *Note there is 12 inches in 1 foot*

Depth= 8in * (1ft/12 in) = 2/3 ft= 0.666... ft

Volume= Length * Width * Depth

Volume= 4ft *1ft * 0.666...ft

Volume= 2.666...ft³

Convert from cubic feet to gallons: *Note there are 7.5 gallons in 1 cubic foot

Volume= 2.666...ft^{3 *} (7.5 gallons/ ft³) = 20 gallons

Answer 2

4 ft by 1 ft by 8/12 ft =

4 ft by 1 ft by 2/3 ft =

8/3 cubic feet is the volume

8/3 cubic feet * 7.5 gallons per cubic foot = 8* 7.5/3 = 8 *2.5 = 20 gallons
