Missing edge from the volume
The question
cm
Missing edge of a box, volume 175
How it works.
5 × 7 × x=175
5 × 7=35
175 ÷ 35=5
- 01
The volume of a box is its three edges multiplied: length × width × height. You have the width (5), the depth (7), and the volume (175).
- 02
Multiply the two edges you know first: 5 × 7 = 35.
- 03
Then the missing edge is the volume divided by that: 175 ÷ 35 = 5.
