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.
