Question

a fish tank in the shape of a rectangle prism measures 6 ft by 5 ft by 1.3 ft about how many gallons of water will it take to fill the tank 3/4 full

Answer 1

About 219 gallons (to the nearest gallon) will be 3/4 full

Firstly, we need to calculate the volume of water that the tank will take

Mathematically, this is the product of the three sides of the tank

We have this as;

`6*5*1.3=39ft^3`

Now, we need to convert this to gallons

Mathematically, 1 cubic ft is 7.481 gallons

Thus, we have that 39 cubic foot will be;

`39*7.481\text{ = 291.80 gallons}`

Now, we need 3/4 of this volume

Mathematically, we have this as;

`(3)/(4)*291.8\text{ = }218.85\text{ gallons}`
