Geometry and TrigonometryEasy–MediumHeight of a box from its volume
Geometry and Trigonometry practice question
A rectangular box has a volume of 240 cubic centimetres, a length of 8 centimetres and a width of 5 centimetres. What is its height, in centimetres?
Answer: 6
Volume = length × width × height: 240 = 8 × 5 × h = 40h, so h = 6.
Common wrong answers
- If you answered 30
- 30 is 240 / 8, dividing by the length only. Divide by the base area, 8 × 5 = 40.
- If you answered 48
- 48 is 240 / 5, dividing by the width only.
- If you answered 227
- 227 is 240 − 13, subtracting the dimensions. Volume is a product, so divide.
