Luis had a bottle of water in the shope of a rectangular prism that measures 7 centimeters by 5 centimeters by 18 centimeters. It was completely filled with water. Then, Luis drank a 1/4 of the water. How many cubic centimeters of water were left in the water bottle?

Sagot :

Answer:

Luis had a bottle of water in the shape of a rectangular prism that measured 7 centimeters by 5 centimeters by 18 centimeters. The volume of the bottle was 630 cubic centimeters. After Luis drank a quarter of the water, he drank 157.5 cubic centimeters. Therefore, 472.5 cubic centimeters of water were left in the bottle.

Step-by-step explanation:

1. Calculate the volume of the bottle:

- The bottle is shaped like a rectangular prism with dimensions 7 centimeters by 5 centimeters by 18 centimeters.

- To find the volume, multiply these dimensions together: 7 × 5 × 18.

- This gives a volume of 630 cubic centimeters.

2. Determine the amount of water Luis drank:

- Luis drank 1/4 of the water in the bottle.

- To find out how much water this is, divide the total volume by 4: 630 ÷ 4.

- This calculation gives 157.5 cubic centimeters.

3. Calculate the amount of water left:

- Subtract the amount of water Luis drank from the total volume: 630 - 157.5.

- This gives 472.5 cubic centimeters of water left in the bottle.

So, after drinking a quarter of the water, 472.5 cubic centimeters of water were left in the bottle.
